The Which? Car survey is the biggest of its kind. An amazing 66,669 owners told us about their cars last year.

As part of the Which? Car Survey, we ask motorists about the reliability of their cars and, using that data, inform car buyers which have the best track records.

Here are the results from last year’s Which? Car Survey for the most reliable large cars, both new and used.

The 2011 Which? Car Survey is currently underway, so fill in a few details about your car and you'll be in with the chance of winning £5,000.

The survey is open to everyone, but the results will only be available to Which? members.

Most reliable large cars

Using our 2010 Which? Car Survey data, we’ve compiled the top five most reliable new large cars and top five most reliable used large cars. 

New cars are models that were on sale new in 2010 and are up to three years old. For the purposes of our survey, used cars are aged between four and eight years old. 

Where a particular model appears more than once (Lexus IS), this is due to two different generations being included in the same time period.
