2008 BMW 5 Series Sedan 535xi 4dr Sedan AWD (3.0L 6cyl Turbo 6M)
Overcomplicated & Unreliable
 My 2008 535xi has 50,000 miles on it. There always seems to be something going wrong with it every few months.It has been one of the most unreliable cars I've ever owned, but when it is working it is a blast to drive. Even the simplest repairs are ridiculously expensive, and you are often forced to going to the dealer as most independent shops cannot work with the BMW computer system.I don't know what they were thinking when they designed idrive. It takes an engineering degree to change radio stations through idrive. I guess over engineering is the BMW way.This will probably be my 1st and last BMW...
