133 comparisons, each on real DVSA MOT first-time pass rates, age-adjusted, alongside the faults each model is actually prone to. Where the data does not separate two cars, the page says so rather than picking a winner.

A worked example

This is what a comparison looks like — two cars live on Autoza right now, side by side. The last row is each model’s DVSA MOT pass rate, measured against the national fleet re-weighted to that model’s own age profile rather than the 77.3% all-ages average, because a raw pass rate mostly measures how old a model’s fleet is.

Pass rates: DVSA MOT anonymised test data, Open Government Licence v3.0 — class 4 tests in Great Britain only, where a pass with rectification at the station counts as a pass. DVSA’s own initial-test measure counts that as a failure, so its headline figure is lower. Testing in Northern Ireland is run separately by the DVA under its own rules. See the full reliability table for 55 UK models.

Frequently Asked Questions

How do I compare cars side by side in the UK?
Open any listing on Autoza and select "Add to compare", then add up to four cars from any make, model or year. Return to this page and you will see price, mileage, year, fuel, gearbox and, for the models we hold DVSA data for, the model's MOT pass rate, plus engine size, body style and the seller where the advert gives them lined up column by column. No account or sign-in is needed.
How many cars can I compare at once?
Up to four at a time. Beyond four, the columns get too narrow to read side by side, especially on a phone.
What should I actually compare when buying a used car?
Price and mileage are the obvious ones, but the figures that separate two similar cars are usually the running costs: the VED (road tax) band, which depends on CO2 emissions and the date the car was first registered; whether it is liable for the London ULEZ or a Clean Air Zone charge; insurance group; and MOT history. A cheaper car with a worse tax band and a weaker MOT record often costs more over three years.
Which used cars pass their MOT most often?
Across 3.46 million DVSA class 4 tests sampled in Great Britain, the average car passes its MOT at the first test 77.3% of the time, counting a pass with rectification at the station as a pass — DVSA's own initial-test measure counts that as a failure and so reports a lower figure, and the spread between models is wide — the weakest of the 55 models we track, the Renault Megane, passes 60.9% of the time. Raw pass rates flatter models that are simply younger, so the ranking worth reading is the age-matched one, where each model is measured against cars of its own age. Our guide to the most reliable used cars sets out that table in full.
Do these comparisons cover running costs as well as reliability?
Partly. Each head-to-head page sets the two models’ DVSA MOT records beside the fuel economy our model guides quote and how vehicle tax applies to them, and says which is more economical where the figures allow. Those are ranges by engine, not a costed total for one car. For what a specific car costs to keep on the road, use the car tax calculator, the EV charging cost calculator or the affordability calculator, each of which works from the published rate rather than an average.
How much is road tax on a used car?
It depends on when the car was first registered. Cars registered from April 2017 pay a flat standard rate from the second year, with a higher first-year rate based on CO2. Cars registered between March 2001 and March 2017 sit in CO2 bands, so two similar cars can differ by hundreds of pounds a year. Cars registered before March 2001 are taxed on engine size. Our car tax calculator gives the figure for a specific car.
Can I compare cars by registration number?
Not yet — today you compare cars from live Autoza listings rather than by entering a registration. You can look up any UK vehicle’s MOT history free on GOV.UK in the meantime.
