Re: Bollocks.
I avoided BMWs for years, on the basis that BMW drivers were wankers. Then I drove one, and realised it was actually really very good. So I turned the logic on its head, concluding "You're a wanker, you might as well have a BMW"
Nowadays I have an Audi A7, which is far away the best car I've ever had.
Frankly, "All <x> drivers are <y>" generalisations are pointless and reveal more about the people who cite them.
