JD Power Survey 2011 - The results

This exhaustive poll records the judgements of 16,840 motorists – car owners whose opinions have been formed over a combined total of almost 300 million miles.

They rated their cars in minute detail so that future buyers will know what potential purchases are really like to live with.

The JD Power survey assesses nine classes of car, from city cars to executive cars and SUVs.

They’ve been judged by the same criteria, including mechanical reliability, desirability, running costs and dealer service.

Here are the final results and how all the individual cars and manufacturers rate against each other.
