Fields returned

How do I check a car spec by reg?

Send the registration to this endpoint. It resolves the plate to the individual vehicle and returns the equipment the manufacturer fitted to it, grouped by category. No VIN, trim code or model year needed at your end.

What does a car spec check actually show?

Standard equipment for the trim, plus the optional extras specified when that car was ordered: things like a panoramic roof, upgraded audio, driver assistance packs or larger wheels. Paid options carry the manufacturer list price where one was published.

Is this different from a trim lookup?

Yes, and it is the difference that matters. A trim table tells you what a model could have been ordered with. This tells you what this particular car has, which is what moves a valuation, an insurance group or a parts match.

Which vehicles are covered?

UK vehicles registered with the DVLA. Coverage of optional equipment is deepest on mainstream marques from roughly 2005 onward, and thins out on older, imported or low-volume vehicles.
