What car to get?

So heres the deal...i have 18,000 to spend on a car. i want something with reletively low miles. like pry under 65,000 for sure it has to be realiable. i want it to have a nice interior and shit like leather and stuff like that. and i want it to be fast. like im thinkin 0 to 60 in under like 6.5 for sure. any suggestioins will help
thanks

Why not a Saab 9-2 turbo (essentially rebadged WRX)? Fast as a WRX with the Subaru reliability and the luxury toys found in any Saab.

im lookin at gettin a 2004 pontiac gto. what is everyone's opinion of this car?
thanks

I think they look really good, lots of power on tap, and its less than stellar popularity gives it a good price tag. Go for it.
