How an Accident on Your Carfax Affects Your Car's Value

The thing that moves an offer is not the accident. It is the claim amount attached to it. Two cars can both show an accident on the report and be priced thousands of dollars apart, because the entry is not what gets priced. The claim is.

Across our own buying it works out at roughly $1,000 off for every $5,000 of claim. Here is where that number comes from, what it does not cover, and why a good repair does not take it back off.

How much does an accident on your Carfax lower your offer?

Start with a car we would pay $20,000 for with nothing on the record. With a $5,000 claim against it we are at about $19,000. At a $10,000 claim, about $18,000. At $15,000, about $17,000. Every $5,000 of claim is about $1,000 off the number.

That is a working rule rather than a formula. It tells you the size of the thing before you get emotionally involved with it. Most sellers brace for the whole accident, and the whole accident is not what is being priced.

It also sits alongside everything else rather than replacing it. We price on three things: kilometres, claims, and the condition of the car in front of us. A claim is one input into that, not a penalty bolted on at the end of it. The rest of what moves a number is covered in what affects your car's value.

Why does a properly repaired car still lose money?

Because the entry on the report does not describe the state of the car. It describes the car's history, and the history goes with the car into the next sale rather than staying with you.

What we do with a claim car is the clearest way to see it. We buy to sell on, so the number we can pay is set by what the car is worth to the buyer after us, and that buyer is reading the same report we read, against the same clean record cars we were reading it against. The repair invoice is not part of that comparison. Nobody after you is buying the repair.

Financing is part of what keeps the gap there. A claim affects what the car can be financed at and by whom, and that follows the vehicle rather than the bodywork. The panels can be flawless and that conversation is still a different conversation than it would have been.

Repairing the car was the right call, and on a car you were keeping it was money well spent. It is just not money that comes back at the sale, because nobody is buying the repair. They are pricing the record.

The record is rarely even the first thing that gives it away. Every car we come out to gets walked first, around the body, looking for dents, scrapes and anything that was not in the photos. Paint that does not quite match in daylight, a seam that runs wide at one end, a panel sitting proud of the one beside it: the walk finds those, and the report only confirms what it already suggested. Neither the quality of the repair nor your account of it changes what those two things agree on.

Is there a claim amount that makes a car unsellable?

No, and the ladder keeps going well past where most sellers assume it stops. The last car we bought before writing this was a 2021 Mercedes C43 carrying a $29,000 claim. The seller had his insurance records with him, knew exactly what was on the car, and would not drop a single dollar. We paid his number. We were at the bank with him about ninety minutes after first looking at the car.

A large claim changes the price. It does not decide whether the car sells.

What happens if the car is salvage or rebuilt?

That is a different order of magnitude and it is not on the same ladder. We do buy rebuilt vehicles, at roughly half of what the same car would be worth with a clean history.

Alberta records five statuses against a vehicle: Active, Salvage, Rebuilt, Non-Repairable and Unsafe. If a Salvage vehicle is repaired and passes a Salvage Vehicle Inspection, it becomes Rebuilt, and it stays Rebuilt. There is no later point at which it quietly becomes an ordinary used car again.

How do you find out what your claim was actually worth?

The report tells you an accident happened. The dollar figure is what prices it, and your insurer is the reliable source for that figure. Turning up with the claim record leaves nothing to establish and nothing to take anybody's word on, and an appointment on a car that is exactly as described can be done in ten to fifteen minutes. The C43 seller held his price precisely because he could show what the claim was, which meant he already knew what the car was worth with it.

Is it better to disclose it or let the buyer find it?

Disclose it. We ask about claims and accidents before we come out and we pull a report either way, so an undisclosed claim gets found rather than avoided. More than once we have been told a car has nothing on it and then found a total loss claim sitting there. In our experience that is usually not somebody trying it on, because a car can be bought used with a claim already against it and nothing about driving it would tell you. What a surprise like that does to the number at the door is the main reason an offer moves at the appointment.

None of this asks you for a spotless record. It asks for an accurate one. The offers that hold from the screen to the driveway are the ones made against the car that is actually there, claim and all.
