I had a BMW and a TVR at the same time.
I had a BMW and a Scooby 22B at the same time (briefly!).
I had a BMW and a Peugeot at the same time.
I had a BMW and an Alfa at the same time.
I had a BMW and an Audi at the same time.
This shows how generalisations and perceptions of such drivers, based on nothing more than the car they are sat in at any one time are simply idiotic with no foundation more often than not. TVR and Alfa drivers are often held up by other such fools as "good chaps" who appreciate the purity of their cars, yet I was the same bloke each time I drove any of them. That bloke was not someone who undertook, sat 5 feet from your bumper, raced around with his shades on and his window open while listening to some jiggy jiggy 'music', worked selling houses or thought £40K per annum was a well off wage and anyone who didn’t earn that much was to be derided, walked over or looked down on.
No question that many people who drive BMW’s buy them because they have odd aspirations or feel they need to be seen in one to fit in with their image, but in my experience the VAST majority of BMW drivers, especially in the newer ones buy them because they have driven several different types of car and simply prefer the BMW for what they seek, and improving their image is not one their reasons.
Have I ever sat in the outside lane of a motorway and flashed someone who has sat there for miles, with nothing inside them or without looking in their mirror during that time while in a BMW well yes, and while in about 10 others types of car too. Do I get nervous when I see a Muslim on an underground train with a ruck sack?
