Anything with 'TDi' on the back. I can't be bothered to shy away from the obvious stereotype: It's the late twenties to mid thirties ginsters munching sales rep. They used to be found in the BMW 318i, but it appears the diesel engined 'dub cars are the new road rocket. This is compounded with such balding drivers mistaking the woosh of torque at 2200rpm for Ferrariesque performance (briskoda, anyone?).
Failing that, the Merc Sprinter quite often takes up the entire rear view. That's allowed tho
