Every VIN we decode identifies a make and model. Counting how many distinct models each brand spans, against how many lookups it draws, describes how a range is built.
| Brand | Distinct models | VINs | Per model |
|---|---|---|---|
| BMW | 104 | 1,538 | 14.8 |
| RAM | 10 | 780 | 78.0 |
A catalogue against a shortlist
BMW's 104 models cover saloons, estates, coupés, convertibles, four SUV families, electric variants and performance versions of most of them — each with its own designation. Attention spreads thin across the range.
RAM sells pickups and vans. Ten nameplates absorb 780 lookups, and each one is checked five times as often as a typical BMW.
Neither approach is better. They're different bets: BMW covers every niche and asks buyers to navigate it, RAM covers few niches and owns them.
What it means for a used buyer
Wide ranges mean thin data per model. With 104 models, many BMW variants have very few examples for sale at any moment — and we found 61% of models have under 100 listings across all 37 model years. Valuing a rare variant is guesswork.
Narrow ranges mean deep comparables. A RAM 1500 has thousands of listings, so pricing is precise and negotiation has a factual basis.
Parts and expertise follow concentration. A model shared across a huge production run has more independent specialists and more remanufactured parts than a niche variant of a broad range.
The distribution of attention is stranger still
Across all brands, lookups follow a power law rather than anything resembling an average. 259 VINs — 0.9% of the total — account for 41.3% of every check ever run. The most-checked vehicle is a 2003 Chevrolet Silverado at 9,497 lookups.
Meanwhile 8,981 VINs were checked exactly once and never again. Most cars get one look; a tiny number get returned to obsessively.
And 3.0% of what people check isn't a car at all — 375 motorcycles, 357 heavy trucks and 172 RVs, spanning 260 makes, 120 of which appear a single time.
What to do with it
On a broad-range brand, verify the exact variant. Trim and body style drive price heavily when comparables are thin, and listings describe them loosely. A VIN check decodes what a car actually is.
On a narrow-range brand, use the depth. With thousands of comparables, an out-of-line price is visible immediately.
We looked at how checking behaviour differs by brand in a Tesla VIN gets run 42 times and a Ford VIN 11.
Frequently asked questions
Which brand has the most models?
BMW, spanning 104 distinct models across 1,538 decoded VINs — about 15 lookups per model. RAM covers just 10 models across 780 VINs, roughly 78 each.
Does a wide model range make a car harder to value?
Yes. With 104 models, many variants have very few listings at any moment — and 61% of all models have under 100 listings across all 37 model years, which makes pricing a rare variant guesswork.
How concentrated are VIN lookups?
Extremely. 259 VINs — 0.9% of the total — account for 41.3% of every check ever run, while 8,981 were checked exactly once. The most-checked vehicle is a 2003 Chevrolet Silverado at 9,497 lookups.
Do people check things other than cars?
3.0% of lookups aren't passenger cars — 375 motorcycles, 357 heavy trucks and 172 RVs, spanning 260 different makes, 120 of which appear exactly once.

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.
510 People Asked for a Pre-2010 Window Sticker. None Exists.
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.
