Dividing each brand's share of VIN lookups by its share of listings gives a ratio: above 1 means people check it more than it appears on the market.
| Brand | Check vs market share | Lookups |
|---|---|---|
| Mercedes-Benz | 8.10x | 1,212 |
| Porsche | 3.38x | 619 |
| Tesla | 2.96x | 502 |
| BMW | 1.77x | |
| Toyota | 1.07x | On the market rate |
| Subaru | 0.64x | |
| Chrysler | 0.53x |
It's the opposite of where the problems are
Chrysler averages 7.01 complaints per listing and gets checked at half the market rate. Porsche averages 0.85 complaints per listing and gets checked three times more than it appears.
If checking tracked risk, those numbers would be reversed.
What it actually tracks is the size of the mistake
A Mercedes buyer is spending more, on a car whose repairs are notoriously expensive, often without a warranty. Getting it wrong costs thousands. That justifies five minutes of research, and the behaviour follows.
A Chrysler buyer is spending less on a car they assume they understand. The downside of a mistake feels smaller — so the check feels optional, even though the complaint record says the odds of a problem are eight times higher.
At the model level the same pattern: Mercedes C-Class 6.49x, BMW X7 5.92x, Tesla Model Y 5.52x, Ford Bronco 4.99x. Aspirational and expensive, all of them.
The same inversion appears by age
Cars from 2020 onwards draw 50.5% of all lookups while making up 18.6% of listings — a rate of 2.71x. Ten-to-fifteen-year-old cars sit at 0.50x, checked half as often as they're sold.
Yet that older band is exactly where odometer rollbacks, unrepaired recalls and rebuilt titles live. A three-year-old car has a short, clean history by definition. We measured the same thing from another angle in people run 217,000 checks on cars built since 2020.
One more detail worth knowing
Of 30,657 VINs people have checked, only 213 also appear in our listing data. People overwhelmingly check cars they're already standing in front of — at a dealer, mid-negotiation — rather than cars they're browsing.
That's late in the process. A branded title discovered at the dealership has already cost you the trip and put you in a position where walking away feels harder than it should.
What to take from it
Check by risk, not by price. The cheap, familiar, high-complaint car deserves the check more than the expensive one, not less.
Check older cars especially. The 10–15 year band has the most history to hide and gets the least scrutiny.
Check before you travel, not at the forecourt. A VIN check takes seconds and works from a listing photo of the windscreen plate.
Frequently asked questions
Which car brands get VIN-checked most?
Mercedes-Benz at 8.1 times its share of the market, then Porsche at 3.4x and Tesla at 3.0x. Toyota sits at 1.07x, exactly market rate, while Subaru runs 0.64x and Chrysler 0.53x.
Does VIN checking track actual risk?
The opposite. Chrysler averages 7.01 complaints per listing and gets checked half as often as it's sold, while Porsche averages 0.85 complaints and gets checked three times more. What it tracks is how expensive the mistake would be.
Which cars should be checked most?
Older, cheaper, high-complaint vehicles — the ones currently checked least. Cars from 2010–2014 are looked up at half their market rate despite being where rollbacks, unrepaired recalls and rebuilt titles concentrate.
When do people usually run a VIN check?
Too late. Of 30,657 checked VINs only 213 also appear in listing data, meaning people check cars they're already standing in front of at a dealer rather than ones they're browsing from home.

The Code on Your Window Sticker Says T3B70. Here Is What It Means.
Every window sticker carries an emissions certification code, and almost nobody can read it. The codes are not arbitrary: one number inside them tells you how clean the car is, and it has been falling.

The original window sticker is the single best document about how a car was sold. Whether it still exists depends almost entirely on one thing, and it is not the make, the model or the condition.
