None of these cars has particularly good reliability records, I'm afraid. And the maintenance and repair costs will always be reflective of the vehicle's price when new (£30,000+). It's also worth noting that the average car in the UK is scrapped at 13 or 14 years of age (which is the point at vehicles start to become uneconomical to repair).

You can see all of the reported problems with these vehicles in the good/bad section of our reviews below:

If you are looking for a reliable and premium used car, my recommendation would probably be the Lexus IS. Lexus always performs strongly in our annual Satisfaction Index for reliability and comfort: www.honestjohn.co.uk/lexus/is/
