I love sweet cars.

Cars I can (and would) buy for under $20,000 

(assuming I needed one, which I don't for at least another year+)

Porsche 968/968 Cabrio

Audi TT/TT Cabrio

Mercedes SLK

BMW M3

Lexus IS

Mini Cooper S

Mazda RX-8

Mazda Miata

Mazda 3

Nissan 350z

Infiniti G35

VW GTI

Scion tc

Honda Accord Coupe

Obviously year and mileage is a significant factor.  But I could own a Porsche or a 2000+ Mercedes, Audi, Lexus or BMW for under $10k!  Wow.  I can't wait.  But I think I want a TT, an RX-8, or an M3.  Assuming Tiffany already has a Mini Cooper :)
