Step one
The plate finds the car
Nine fields come back against your registration from the DVLA — make, model, year, engine, keeper count and MOT history. What the plate says is what gets priced, not what you typed.
Enter a registration and a mileage and the index prices your car against every comparable one sold in the last 90 days. It costs nothing, it takes about two minutes, and nobody calls you afterwards.

Step one
Nine fields come back against your registration from the DVLA — make, model, year, engine, keeper count and MOT history. What the plate says is what gets priced, not what you typed.
Step two
The reading is set against the depreciation curve for that exact model, not a flat pence-per-mile guess. High-mileage examples are docked where the sold records dock them.
Step three
Every comparable car sold in the last 90 days forms the cut, and forecourt asking prices are excluded. An asking price is a wish; a valuation is not a wish.
Step four
Not one flattering number: the band your car sits in, the median for the cut, and how far either side. If the figure is unflattering, the page says so.
What the figure covers
The plate. Everything the DVLA returns against your registration — identity, keepers, MOT history — is the car that gets priced.
The mileage. Adjusted on the model’s own curve, where the sold records say it hurts and where it doesn’t.
The 90-day cut. Every comparable sale of the last 90 days, including the cheap ones. Nothing is trimmed to flatter the figure.
The placement. The band, the median, and your car’s position between them — printed, with the count of records behind each band.
The paper trail. File the car afterwards and the same figure prints on its record, so buyers see what you see.
All five come from sold records. None comes from a dealer’s opinion, and none is for sale.
What it cannot tell you
/cars/…The condition Two identical Golfs are not the same Golf. The index prices the record; only you know what the scratch cost.
/submit/The options list Every extra is worth something to somebody and little to the cut. The index prices the average; your panoramic roof is your problem.
/specialists/…The work it needs A cambelt due next month is invisible to the plate. Price it into your expectations, because buyers will price it into theirs.
/used-cars/This afternoon’s market The figure is a 90-day measurement, not a forecast. The cut moves weekly, so re-run it the week you actually sell.
What the figure is, what it isn’t, and what happens to the valuation if you go on to sell.
