Make, model, colour and engine
These are the easiest fields to check and the first line of defence against a mismatched car. A plate belongs to one vehicle. If the record says a silver 1.6 petrol hatchback and the car in front of you is a black 2.0 diesel, one of three things is going on: the advert is wrong, the plates have been swapped, or the seller is not being straight with you. Do not go further with the second or third until you have a clear, documented explanation. A respray is legal and common, but the owner should be able to tell you when and why it happened.
Fuel type and engine size
Fuel type tells you more than you might expect. A diesel registered before around late 2015 generally falls below Euro 6, and that matters if you drive into London or Bristol. Engine size helps you sense-check the price: a small-capacity engine in a car advertised as a performance model is worth querying.
Year of manufacture and first registration
The month of first registration is the date the car first went on the road in the UK. It sets the clock for the first MOT, which is due by the third anniversary of registration, and then every 12 months. If the seller says “it’s a 2019 car” and the record shows first registration in 2016, you are looking at an older car than advertised, and the price should reflect that. The age also fixes the likely emissions standard, which is why the Euro field sits close by.
Tax status and due date
Tax is the field that surprises buyers most. Vehicle tax is not transferred when a car is sold. The new keeper must tax the car before driving it on the road, so a car showing “Taxed” today will need fresh tax in your name the moment you buy it. A status of SORN means the owner told DVLA the car is off the road, and it cannot be used on the road until it is taxed again. “Untaxed” on a car that is being driven is a problem for the seller, and for you if you buy and drive away without sorting tax first. The standard rate is set each tax year, so check the current figure on GOV.UK rather than relying on an old number.
MOT status and expiry date
A valid MOT means the car passed its last test and the certificate has not yet expired. It does not mean the car is in good condition today. An MOT is a snapshot of roadworthiness on the day of the test, covering the items DVSA tests, and it says nothing about the clutch, the gearbox, the service record or the engine’s long-term health. Look at the expiry date and think about timing. If it runs out in a fortnight, you will be paying for a test soon after you buy. You can have the test up to a month minus a day before expiry and keep the same renewal date, which our guide on how early you can get an MOT explains in full. Driving without a valid MOT can bring a fine of up to £1,000, with exceptions for driving to a pre-arranged test or to a repair.
Euro status and emissions
Euro status is the emissions standard the vehicle was built to. Broadly, petrol cars need Euro 4 and diesel cars need Euro 6 to avoid the £12.50 daily ULEZ charge in London, and the same logic applies to the Clean Air Zone charges in Birmingham and Bristol. Our estimate uses the Euro status and fuel type on the record, but the official TfL and council checkers have the last word, so confirm there before you travel. Our ULEZ checker and Clean Air Zone checker explain the rules in detail.
The export marker
The marked for export field shows whether DVLA has been told the vehicle is being, or has been, exported. A vehicle showing this flag should not simply be on sale in a UK car park. There can be innocent explanations, such as an administrative error or a vehicle that returned, but you should get a clear, documented answer from the seller before handing over money. If they cannot explain it, treat it as a reason to walk away.
The latest V5C issue date
Where the record shows the date the most recent V5C log book was issued, use it as a conversation starter. A date from last week simply means the document was reissued, which happens when a keeper changes, an address changes or a document is replaced. A very recent date on a car the seller says they have owned for years is worth a polite question. It is not proof of anything on its own.
