Looking for another cheap runaround the moment but still something with a bit of class and good looks.

Looking at a few E46 saloons (4 door) or coupes on ebay etc theres a fair few on there from an X reg up to 52 reg for around £1000 - £1500.

In owning nearly 100 cars ive never owned a BMW. Anything to look out for or avoid on when it comes to them?
