Fill in the Which? Car Survey 2014

Which? Car Survey 2014

The Which? Car Survey is your chance to tell us about the car you own.

Last year, 47,572 people filled in the survey, telling us about a total of 57,182 cars they own. That makes the Which? Car Survey the biggest car reliability survey in the UK.

This collection of data means we can tell you more accurately than anyone else which cars are the most and least reliable, how much they could cost you in repairs each year and what the most common faults are.

And, unlike any other reliability survey, the results feed directly into our car reviews. If a car has a poor reliability track record, it can’t be a Best Buy.

The survey takes just 15 minutes to complete and covers reliability, customer satisfaction, car servicing, car sales and breakdown assistance. Filling it in will automatically enter you into our free prize draw to win £2,500 - enough to cover your fuel costs for a whole year*.
