I drove in a Dodge Viper RT/10 convertible (i think 1997 maybe was the year of the car) which was just awesome to say the least. You'd try to get in the seat but would almost fall in because the car is so low to the ground and when you're sitting in it feels like you're laying back so far. But seriously as soon as you're in it just feels like it's so fast already before you even start driving. But that would be the most expensive car ive personally driven in (didn't get to drive it of course, just a passenger)
edit - and as for a price that car would be about $65 000 USD
