Car Spec Check Guide: What Vehicle Data Tells You

A car specification check, loosely known as car spec check, is the information about the vehicle that you may not usually consider. This includes specifications such as wheelbase, cargo capacity, and basic dimensional factors of the vehicle such as weight, and height. Although not commonly the most vital information you require about a new car, it is still information that you should consider familiarising yourself with, before making a purchase.

We get all our information from the DVLA, so you can have peace of mind, knowing that we can access all of the information that your vehicle of interest was listed as when it was first registered. The beauty of car spec information, is that it technically should not change, regardless of the number of previous keepers, or wear and tear. All you need is the registration number!

All of this information will be provided on a fact sheet if you are purchasing from a yard, but if you are proceeding with a private sale, simply enter the registration number here, and we will do the rest for you!

These handy checks also include:

* MOT check, and history
* Car Tax and rates
* Technical information about the car
* Last known mileage record
* Specifications of the vehicle

Original guide plus spec checks

Use the specification to verify value and identity

A car spec check is not just trivia. Specification affects value, insurance, emissions, tax, parts and whether the advert describes the real car.

Details to compare

Check the registration result against the advert, V5C and vehicle. Spec mismatches can be innocent, but they should be explained before payment.

• Make, model, trim and body style.
• Engine size, fuel type and emissions.
• Colour, doors and transmission.
• VIN and engine-number consistency where relevant.

Why it matters

A higher trim, lower emissions band or different engine can change the price. A mismatch can also point to advert errors, private-plate confusion or identity problems.

Pricing and running-cost checks

Use the specification to sense-check valuation, road tax, emissions-zone exposure and insurance. A car advertised as a desirable trim or engine should be supported by the registration record and paperwork.

• Compare trim and options with the asking price.
• Check tax and ULEZ implications.
• Confirm fuel type before estimating running costs.
• Ask for evidence if the advert claims rare options.
