Which? Don't Buy cars

We subject every car to hundreds of lab and road tests, ensuring you know exactly how well it performs for safety, practicality and more.

If a car scores particularly badly, it will be a Which? Don't Buy, meaning you should spend your money on a different model.

Euro NCAP crash tests

We helped to establish Euro NCAP in 1996 and continue to partner with the crash-test organisation regarding safety issues.

All cars tested by Euro NCAP are given an overall star rating out of five. For any that receive two stars or fewer, we automatically make them Don't Buys, as we believe modern cars should get at least three stars to be considered safe.

Any vehicle that scores three stars can't be a Best Buy.
