The reason for change
The concours field has evolved.
M100 was created because the automobiles, the entrants and the events themselves are changing.
M100 was not developed from the perspective of one country or one national judging tradition. It grew from practical experience at concours events around the world, where different judging cultures, event formats, collector communities and automobiles reveal both shared standards and differing practical needs.
Major international concours now bring together pre-war automobiles, post-war icons, historically significant competition cars, youngtimers, supercars and hypercars. A Lamborghini Miura and a BMW M1 are accepted classics. The McLaren F1 is more than three decades old. The Bugatti Veyron is moving from technological landmark toward historic automobile.
These cars do not share the same construction, use patterns or preservation requirements. A traditionally coachbuilt car may be restored through metalwork and craftsmanship. A carbon-composite supercar may instead depend on bonded structures, electronic systems and components that are replaced or reconstructed with modern technology.
Different automobiles require different questions — but the same commitment to excellence.
A judging system intended for modern multi-marque events must therefore remain exacting without becoming rigid. It must understand what correctness means for each category and still identify the best automobile in the class.
The central principle
The automobile is more than the sum of its parts.
A concours car is not merely an inventory of components. It is a complete object with an identity, a purpose and a history.
That identity is created by the relationship between design, engineering, materials, craftsmanship, provenance, use, preservation, restoration and historical context. Two automobiles may appear equally correct when their individual components are considered in isolation, yet they may not be equal as complete cars.
Judging must consider not only what a car is made from, but what the complete automobile represents.
M100 therefore places every technical observation within the context of the whole vehicle. This does not excuse incorrectness or diminish detailed examination. It ensures that a minor deviation remains proportionate and that exceptional design, technological impact, competition history or provenance can influence the final evaluation where justified.
The objective is a result that reflects the automobile itself: not simply the mathematical total of its individual parts, but the quality and significance of the complete car.
Why 100 points?
One hundred points represent the automobile as a whole.
An automobile consists of far more than one hundred parts. M100 uses a 100-point scale to express the overall evaluation as a percentage, bringing together technical quality, authenticity, condition and significance in the context of the car being judged.
Technical correctness, authenticity, condition and workmanship form the indispensable foundation. But an automobile worthy of the full 100 points must also embody the qualities for which we preserve automotive heritage: outstanding design, engineering achievement, provenance, historical importance, technological influence and cultural significance.
These factors are not decorative additions to the technical result. They help define the identity and importance of the automobile itself. M100 therefore uses the complete 100-point scale to connect measurable quality with the reasons the car matters.
One hundred points mean one hundred per cent: technically excellent, historically meaningful and complete as an automobile.
This principle does not allow significance to disguise a technically inadequate car. It ensures that among technically excellent automobiles, the final evaluation can recognise the qualities that elevate a correct car into an important piece of automotive culture.
What M100 preserves
Modernization does not mean lower standards.
M100 is an evolution of established 100-point judging, not a rejection of the knowledge and discipline on which concours judging was built.
Authenticity, correctness, condition, workmanship and informed examination remain fundamental. What changes is the way those criteria are balanced across automobiles from very different periods and disciplines.
01
Correctness
A car must remain credible to its period, identity and intended specification.
02
Proportion
A minor deviation should remain minor and should not overwhelm the quality of the complete automobile.
03
Significance
Design, innovation, provenance and historical impact help explain why one exceptional car matters more than another.
04
Expertise
The framework supports experienced judges; it does not attempt to replace knowledge or informed judgement.
One philosophy, four formats
The method adapts to the automobile.
M100 does not force fundamentally different vehicles into one generic checklist. Each format asks the questions that are relevant to that category while retaining a common commitment to quality, fairness and the complete car.
95+5
Classic Cars
95 Technical Points establish correctness and quality. Up to five Significance Points may recognise exceptional design, technology, provenance or historical importance.
60+40
Historic Race Cars
Technical correctness to a defined event or race specification is combined with model significance and the competition history of the individual chassis.
50+50
Supercars & Hypercars
Build quality, condition and usability are evaluated together with design, innovation, technology, provenance and individual ownership history.
50+50
Restomods
Judged as built rather than against originality: build quality, integration and usability are evaluated together with design concept, engineering and sound.
One objective
The best overall automobile should win — not merely the car that survives the harshest deduction process.
Frequently raised questions
Clear answers to fair questions.
Does M100 replace traditional concours judging?
No. It builds on the established 100-point tradition and preserves technical examination. It adapts the process for diverse international events where automobiles from different eras and disciplines must be compared meaningfully.
Does M100 make judging more subjective?
Its subjective elements are limited, structured and entrusted to the same experienced judging teams that are qualified to make technical deductions. Best in Show and many decisive concours comparisons have always required informed judgement; M100 makes that reality more transparent.
Can significance compensate for an incorrect car?
No. In the Classic Car format, Significance Points are a tool for distinguishing already excellent automobiles within their class. When technical deductions exceed five points, the car will generally not be strong enough overall for Significance Points to change the outcome.
Why do the categories start from different point bases?
Because points determine the result within a class only. Each category uses a scoring structure suited to its automobiles, and scores are never compared across classes or categories. Best in Show is decided separately, by secret ballot among the class winners.
Why limit deductions to two points per section?
The limit prevents commonly observed over-penalization and keeps an isolated issue in proportion to the complete car. It applies to every M100 judging form — classic cars, historic race cars, supercars and hypercars, and restomods alike. Exceptions remain for fundamental failures such as an out-of-period body or a non-starting engine.
Is M100 simply a modified version of another judging sheet?
No. Familiar inspection areas appear in many systems because the automobile itself determines what must be examined. M100’s category-specific forms, terminology, alphabetical field sequence, colour coding, deduction controls and significance framework were developed independently from extensive practical judging experience.
Why not use one form for every automobile?
Because the meaning of authenticity and preservation changes with construction and purpose. The correct questions for a pre-war road car are not identical to those for a Le Mans race car or a carbon-composite hypercar.
Constructive dialogue
A serious system should welcome serious scrutiny.
M100 is intended to remain a living system, informed by its use at major concours events and by precise, evidence-based technical discussion.
General labels do not improve judging. Specific questions do. If a criterion, deduction, definition or outcome can be improved, M100 welcomes a clear example and a reasoned alternative.
The purpose is not to diminish other systems or the people who developed them. Different events have different needs. M100 exists to provide a proportionate and adaptable framework for events whose fields — and whose audiences — continue to evolve.
Preserve the standards. Widen the perspective. Let the best car win.
Built on tradition. Developed for today.
Why another judging system?
M100 was not created because traditional concours judging was wrong. It was created because the automobiles presented at concours events — and the events themselves — have continued to evolve.
The established 100-point approach provided an important framework for evaluating authenticity, correctness and condition. Those principles remain fundamental to M100.
But experience in the field also raised a broader question:
Does the absence of deductions alone always identify the most important or most deserving automobile in a concours class?
M100 was developed from the conclusion that, in many circumstances, it does not.
An automobile can be technically correct yet relatively ordinary. Another may carry extraordinary design importance, engineering innovation, competition history or provenance while showing minor evidence of use. A judging methodology should be capable of recognising the difference without abandoning objective standards.
Evolution, not rejection
M100 builds upon an established tradition.
M100 does not claim to have invented 100-point concours judging. It deliberately builds upon a judging tradition familiar to experienced concours judges throughout the world. The fundamental areas of an automobile — body, paint, interior, chassis, drivetrain, engine compartment, wheels and functionality — naturally remain part of any serious evaluation.
The development of M100 takes place within that tradition, not outside it. What changes is the way the observations are weighted, interpreted and brought together.
M100 introduces proportionate technical deductions; a controlled recognition of significance; dedicated methodologies for fundamentally different categories of automobile; greater consideration of provenance, design, engineering and historical impact; practical acceptance that important collector cars should remain usable; clear guidance intended to support consistency between judging teams; and a judging process designed to make the final result understandable and defensible.
The judging sheet is not the system. The methodology behind it is the system.
The complete automobile
100 points should represent the complete automobile.
M100 interprets 100 points as the 100% automobile. That means more than the absence of faults.
Authenticity and correctness remain essential, but they are part of a larger picture that can also include condition, design, engineering, provenance, historical significance, competition history, technological importance and usability.
The relative importance of these factors depends on the type of automobile being judged. This is why M100 does not use one identical scoring architecture for every car.
Three different automobiles. Three different questions.
01
Classic Cars
For a historic road car, authenticity, originality, correctness and condition remain the foundation. M100 retains a predominantly technical assessment while allowing a limited number of Significance Points to recognise exceptional design, engineering, provenance and historical importance.
The objective is not to excuse incorrectness. It is to ensure that a minor detail does not become more important than the automobile itself.
02
Historic Race Cars
A competition car cannot always be understood solely by examining its physical components. What the car did can be as important as what the car is.
M100 evaluates authenticity to the appropriate competition specification and the significance of the model and individual chassis. Competition history becomes part of the evaluation because it is part of the identity of the automobile.
03
Modern Supercars & Hypercars
A restoration-focused methodology creates a different problem when applied to a modern hypercar. M100 therefore combines objective evaluation of build quality and condition with design, engineering, innovation, technological impact and provenance.
The relevant questions include the significance and execution of the design, the technologies and materials introduced, and the model’s importance in the development of the automobile.
Proportion matters
A minor issue should remain a minor issue.
M100 follows a simple principle: a concours judging system needs deductions because correctness matters, but the accumulated effect of small deductions should not automatically overwhelm the quality and significance of an exceptional automobile.
This controlled deduction structure is not intended to make judging less rigorous. It is intended to make it more proportionate.
The more useful question is not “How many faults can we find?” but “What do these observations tell us about the automobile as a whole?”
Cars are part of a living heritage
Important automobiles should remain usable.
Important automobiles should not automatically be disadvantaged because they are driven. Reasonable, discreet measures that improve reliability, safety or practical usability can be evaluated in context where they do not materially compromise the historic character of the automobile.
This does not mean that authenticity is unimportant. It means recognising that an automobile is a functional cultural object. It was designed to move.
Preserving automotive heritage should not necessarily require preserving an automobile in inactivity.
The role of expertise
The judge remains essential.
M100 does not attempt to replace knowledge with mathematics. No judging form can determine by itself whether a component is authentic, whether a restoration is historically appropriate, whether a competition car corresponds to its period specification or whether a particular automobile is historically significant.
Those decisions require experienced judges. The purpose of the M100 forms, deduction guidance and scoring structures is therefore to support expert judgement with consistency and transparency — not to replace it.
The numbers provide discipline. The judges provide knowledge, context and judgement.
A methodology that can continue to evolve
Automotive history did not end in 1960, 1980 or 2000.
Cars that were once considered modern become historic. New construction methods, composite materials, digital technologies and alternative powertrains continue to change the automobile. Concours events will consequently continue to change as well.
M100 was intentionally created as an adaptable methodology rather than a rigid doctrine. Its principles should remain stable:
Authenticity. Correctness. Condition. Quality. Significance. Proportion. Transparency.
How those principles are applied must remain capable of responding intelligently to the automobiles being judged.
The objective remains simple
Make the result more meaningful.
M100 does not exist to make judging easier. It exists to make the result more meaningful.
At the end of the process, judges should be able to explain not merely why one automobile lost points, but why the winning automobile deserved to win.
The best automobile should win — not simply the automobile with the fewest detectable faults.
