Everyone should stop mocking the veyron, I can see why you would hate it but you have to learn how to drive it first. It is so fast for a car on sport tyres that people forget that it isn't on slicks and plow into corners far too quickly. Also in stock form, 30 percent on the power goes to the front wheels, when in real life only 20 percent goes to the front. After doing this, you can actually get some power on oversteer.
Back on topic, I think that the ruf rgt is a dream to drive, so is any Elise or catereraham (until you hit a cone that is)
The worst is probably my tuned yaris vitz thing without a LSD and stock tyres. Understeer is unbelievable
