What Concours Judges Actually Look For (And What It Means for Your Car's Value)

Most people watching a concours assume the judging is a beauty contest — that a row of experts strolls the lawn, decides which car moves them most, and hands over a trophy. That is not what's happening. What's happening is closer to an audit.

Understanding how that audit works is worth your time even if you never intend to park on a fairway, because the standard concours judges apply is essentially the same standard the collector market uses to price cars. Learning to look at a car the way a judge does is learning to look at it the way a serious buyer does.

Every Car Starts With a Perfect Score

Nearly every major concours uses a 100-point deduction system. Your car doesn't climb its way up to 100. It arrives at 100 and then loses ground. Judges subtract for every deficiency they find, and at most events each deduction has to be written down with a specific description of the flaw.

That framing changes everything. Judging isn't about impressing anyone. It's about giving a trained expert nothing to write down.

At Pebble Beach, roughly 100 class specialists work the field, each spending around 20 minutes with every car in their class, and the team has to reach unanimous agreement on first, second, and third. Twenty minutes is a very long time to stare at one engine bay.

They're Not Judging Your Car — They're Judging the Factory's

The biggest misconception in this hobby is that better than original is better. It isn't. The benchmark is the car as it left the assembly line, and judges work from three questions: are the components correct for the era, were they installed the way the factory installed them, and are they finished to the factory's standard?

Good judges know what's wrong for a period as fluently as they know what's right. An electric cooling fan on a prewar car. A modern worm-drive hose clamp. Electrician's tape where cloth loom belongs. A plastic zip tie tucked behind a wiring harness. Cadmium fasteners swapped for hardware-store zinc. None of that is a matter of taste — it's a documented deduction.

Over-Restoration Is a Deduction, Not a Bonus

Nobody in Detroit, Stuttgart, or Coventry built a mirror-finish car. Factory paint had orange peel. Overspray landed in the wheel wells. Inspection marks were grease-penciled onto suspension components and left there. Frames were painted with the engine already in the car, so some surfaces were never fully coated at all.

A restoration that erases all of that — glass-smooth paint on a car that never had it, chrome on brackets that left the plant in black oxide, an engine bay polished like jewelry — reads as inaccurate to a judge, not impressive. Pebble Beach explicitly penalizes over-restoration. It's one of the most expensive mistakes an owner can make, because the money spent creating the problem is the same money that costs the points.

The Consumables Trap

Batteries, tires, hoses, and belts get replaced. Everyone knows that. What catches people is that judges expect the replacements to look like what the car wore when it was new — correct tread pattern and sidewall lettering, cloth-braided hose where cloth-braided hose belongs, a battery with the right case and label instead of a modern parts-store box.

This is where a lot of otherwise beautiful cars quietly bleed points. It's also the cheapest category to fix.

The Car Has to Run

Presentation is only half of it. Many concours include an operations category and require the owner to be present to start the car during judging. Judges check lights, horn, wipers, gauges, and clock. At some events judges won't open a door or a hood themselves — if it isn't shown to them, it isn't scored well.

A trailer queen that doesn't fire on the first turn of the key has already lost to a car that does.

The Points You Can't Restore Your Way Into

Most 100-point systems let judges add a small number of discretionary points — typically up to three — for elegance and presence, or for provenance and historical significance. Those are the points that can't be bought with a checkbook or a paint booth. A documented ownership chain, period competition history, or original build paperwork moves the needle in a way another round of polishing never will.

Best of Show runs on similar logic. At Pebble Beach, class winners advance to a senior panel that chooses on impact rather than raw score — the car that makes the room go quiet.

Where the Money Actually Shows Up

Here's the part that matters if you're buying or selling rather than showing.

The collector market's standard valuation scale runs from #1 Concours down to #4 Fair, and #1 means exactly what it sounds like: essentially flawless, correct materials throughout, among the best examples in the world. Very few cars are truly #1. Most excellent cars are #2.

That gap is where the money lives. Hagerty's five-year data shows condition #1 cars appreciating 32.4 percent against 23.4 percent for condition #4 — close to a ten-point spread in the rate of appreciation, sitting on top of an already higher starting price. In some segments it's far wider. Fox-body Mustangs in top condition ran up 191 percent while rough ones managed 135.8 percent. Porsche 928s: 75.3 percent versus 35 percent. In deeply established markets the spread narrows — 1965-73 Mustangs showed under three points of difference — but the pattern holds. Condition compounds.

The Wrinkle: Sometimes the Best Move Is Not Restoring

The one thing that outranks a great restoration is an original car. Preservation classes have become a fixture on the concours circuit, and the market has followed. Genuinely original examples of rare, desirable cars have brought 75 to 100 percent more than restored equivalents. Even higher-production cars tend to carry a 25 to 50 percent premium when they're truly untouched.

The working standard is roughly 80 percent original factory paint, an original interior aside from consumables, the original powertrain, and an engine bay with its wiring intact. The reasoning is simple and unsentimental: a car is only original once, and no amount of manufactured patina reproduces it.

Which means the most consequential decision in the whole process happens before any work starts — deciding whether a car is a restoration candidate or a preservation candidate. Get that wrong and you can spend six figures reducing a car's value.

How to Use This If You Never Show a Car

Steal the checklist. Keep every receipt, build sheet, and title in one file, because provenance is worth real points and real dollars. Don't chrome what was painted. Buy period-correct consumables — they cost about the same as the wrong ones. Make every switch, gauge, and light work, because buyers test them exactly the way judges do.

A concours scorecard isn't a trophy sheet. It's a valuation worksheet with a ribbon attached.
