What makes FactorySpecs different
Most spec checks show what a model could have been built with. That is the brochure, not the car.
FactorySpecs reads the build record for the individual car from its registration. You see the options that specific car left the factory with and, where the manufacturer records it, what each one cost new: £1,615 for the air suspension pack, £1,230 for the electrically deployable tow bar, £895 for the paint.
Alongside the fitted list you get the model's full option book: every option the factory offered on that trim, with prices. Between the two you can answer the questions that matter. Does it have the pack the advert claims? What did the first owner spend? Is the price fair against a car without those extras?
A seller's advert is only as accurate as the seller. Check the spec before you travel, and know what you are paying for.

Not a history check. Not a brochure.
A history check tells you whether a car is stolen, written off or on finance. Useful, and we sell one. It says nothing about what is fitted.
A spec checker tells you what a model could have. That is the brochure, not the car.
FactorySpecs is the third thing: the factory build of the individual car, option by option, with the price of each. Nobody sells the car you are looking at by the model it belongs to. Don't buy it that way.

Why check factory fitted options?
When buying a used car, the advert might say “fully loaded” or “high spec”, but what does that actually mean? Factory-fitted options vary enormously between individual cars of the same model. Two identical-looking BMWs, Jaguars, or Audis can differ by thousands of pounds in original specification.
FactorySpecs decodes the VIN to reveal exactly what the manufacturer fitted. That means you can verify the seller’s claims, understand whether the asking price reflects the spec, and spot the difference between a base model and a genuinely well-specified car before you make an offer.
Combined with mileage integrity analysis, MOT advisory intelligence, and live market valuations, you get a complete picture of what you’re buying — not just what the seller wants you to see.
Frequently asked questions
How do I check what factory options are fitted to a car?
Enter the UK registration or VIN into FactorySpecs. The system decodes the VIN to identify every factory-fitted option — the actual extras fitted to that specific vehicle at the factory.
What does a FactorySpecs lookup include?
Each lookup returns factory-fitted options with estimated retail values, full MOT history with advisory intelligence, mileage integrity scoring, live valuations (auction, trade, private), keeper history, and a clear buying verdict.
Does it work for electric vehicles?
Yes. FactorySpecs includes EV-specific data: battery capacity, charging specifications, WLTP range, and warranty status. It was built by EV owners for EV buyers.
How is this different from an HPI or MOT check?
Standard checks tell you if a car is stolen or written off. FactorySpecs tells you what was actually fitted at the factory — the options, packs, and extras that affect value and desirability.
Which manufacturers are supported?
FactorySpecs currently decodes factory options for 51 car brands including BMW, Jaguar, Land Rover, Mercedes-Benz, Audi, Volkswagen, Porsche, Volvo, Hyundai, Kia, and many more.
