1. Luxury: Bentley Continental GT

Very luxurious and classy. They look really safe and I've heard they drive great.
2. Supercar: Bugatti Veyron

This is the epitome of a supercar and it's luxurious too. This thing has 1001 HP and is ridiculously fast.
3. Everyday car : 2008 Honda Civic Si
Good gas mileage, easy to upgrade, quick, fun to drive, and it's got the reliability of a Honda. My neighbor has an '06 or '07 and it looks great.
4. Convertible: e46 BMW M3
I know it's not the new model, but this body style looks cooler in my opinion. This just looks like a fun car.
5. Track Car: Ariel Atom

I've heard it's an awesome car. Supposed to be really quick and handle great. Like a Lotus but way better.
