Julian, I also hate the image that BMW and other cars have. Before I opted for the BMW, I test drove a C class Mercedes, Alfa Romeo 156 and Audi A4. Surprisingly the Merc and BMW were very close, but I found the BMW straight 6 simply fantastic
To be honest, I've admired BMWs ever since a friend of mine gave me a lift in a 520i over 25 years ago. They weren't so common then, it's just taken me so long to get to own one.
GTM, I know about 10 BMW owners and not one has any more problems with their cars than other makes (touch wood), you know what they say about statistics. I agree that if something does fail in these, it's likely to cost more. I suppose s/h BMWs are more likely to be abused than certain other makes.
