Understanding Condition Grades: Concours vs Excellent vs Good

Why Condition Is Everything

In the collector car market, condition is the single most important factor in determining value. Two cars of the same make, model, year, and mileage can sell for prices that differ by 100% or more based on condition alone.

But "condition" is subjective -- or at least it was, before the industry developed standardized grading systems. Understanding these grades, what they actually mean in practice, and how they translate to value is essential for any collector.

The Standard Grading Scale

The most widely used grading system in the collector car world is a 5-tier scale. While specific terminology varies slightly between organizations (Hagerty, Hemmings, Sports Car Market), the general framework is consistent:

Concours / Grade 1

The best of the best. A Concours-grade car is essentially perfect -- or as close to perfect as a car can be while still being a real object that exists in the physical world.

What it means in practice:

• Paint is either factory-original in exceptional condition or a professional respray to factory-correct standards
• All chrome, rubber, glass, and trim is in perfect or near-perfect condition
• Interior is original or correctly restored, with no wear, fading, or damage
• Mechanicals are sorted, with no leaks, noises, or deferred maintenance
• Documentation is complete: original purchase records, service history, window sticker
• The car could win (or has won) a concours d'elegance judging event

What it costs: Concours-grade cars typically command a 100-200% premium over "Good" examples. Achieving concours condition on a car that isn't already there can cost $50,000-$100,000+ in restoration, often exceeding the car's value.

Excellent / Grade 2

A beautifully maintained or well-restored car with only minor imperfections. This is the grade that most serious collectors target -- it's the sweet spot between perfection and practicality.

What it means in practice:

• Paint is in very good condition, possibly with a few minor chips or touch-ups that are only visible on close inspection
• Interior is complete and well-preserved, with minimal wear
• Mechanicals are fully sorted -- the car starts, runs, drives, and stops as it should
• Service history is substantially documented
• The car presents beautifully from five feet away and very well upon closer inspection

What it costs: Excellent-grade cars typically command a 40-70% premium over "Good" examples.

Good / Grade 3

A car in respectable condition that can be driven and enjoyed without apology. This is where most collector cars live. A "Good" car is presentable, mechanically sound, and enjoyable to own -- but it has visible evidence of age and use.

What it means in practice:

• Paint shows its age: minor chips, fading, or areas of touch-up are visible
• Interior has normal wear: some patina on the seats, minor scuffs on trim
• Mechanicals are functional but may have minor items that need attention (a small oil weep, a slightly tired suspension bushing)
• Service history may be incomplete but the car has clearly been maintained
• The car presents well from 10-15 feet and is perfectly enjoyable to drive

What it costs: "Good" is typically the baseline for pricing. Most published market values reflect "Good" condition.

Fair / Grade 4

A car that runs and drives but needs work. Fair-condition cars are functional but have significant cosmetic or mechanical issues that affect enjoyment and value. They're often purchased as projects by buyers who intend to improve them.

What it means in practice:

• Paint may have significant defects: fading, peeling clear coat, visible repairs, mismatched panels
• Interior has notable wear or damage: torn seats, cracked dashboard, missing trim pieces
• Mechanicals work but have known issues: a noisy bearing, a smoking engine, a slipping clutch
• Service history is sparse or nonexistent

What it costs: Fair-grade cars trade at 40-60% of "Good" values.

Project / Grade 5

A car that needs substantial work to be usable. Project cars may not run, may not be complete, and may require extensive restoration. They're purchased by buyers who enjoy the restoration process or who need a specific model and can't find anything better.

What it means in practice:

• May not start or drive
• Significant mechanical issues (engine rebuild needed, transmission problems)
• Body may have serious rust, collision damage, or missing panels
• Interior may be incomplete
• Documentation is typically absent

What it costs: Project cars trade at 20-40% of "Good" values, depending on the model's rarity and desirability.

How Condition Affects Value: A Real Example

Consider a 1973 Porsche 911 Carrera RS 2.7 -- one of the most desirable air-cooled Porsches:

| Condition | Approximate Value | |-----------|------------------| | Concours | $1,200,000-$1,500,000 | | Excellent | $800,000-$1,100,000 | | Good | $500,000-$750,000 | | Fair | $300,000-$450,000 | | Project | $150,000-$250,000 |

The spread from Project to Concours is roughly 5:1. For a car this rare and desirable, even a project is worth a small fortune. But for more common collector cars, a project may barely be worth the cost of restoration.

Practical Advice

Buy the best condition you can afford. This is the single most repeated piece of advice in the collector car world, and it's repeated because it's true. A $50,000 car in Excellent condition will almost always be a better investment and a better ownership experience than a $30,000 car in Fair condition that needs $25,000 in work.

Be honest about condition when selling. Overstating condition erodes trust and leads to disputes. The collector car community is small, and reputation matters.

Get a professional inspection. Before any significant purchase, hire a marque specialist to conduct a pre-purchase inspection. The $500-$1,000 cost of an inspection is trivial compared to the risk of buying a car with hidden problems.

Understand that condition is a spectrum. No car fits perfectly into a single grade. A car might have Excellent paint, Good mechanicals, and Fair interior. The overall grade is a judgment call that weighs all factors.

Condition grading is part science, part art, and part negotiation. But understanding the framework gives you a common language for discussing cars, comparing values, and making informed decisions. In a market where the difference between "Good" and "Excellent" can be $50,000 or more, that understanding is worth its weight in gold.
