New Car!

Hey, I am moving to California in August and I plan to spend around $20 000 on a car ( used ). Im looking for a convertible or an SUV, and I am considering an Audi TT roadster 1.8T as this is a car that I can get used and in good shape for my money..I am also considering a Jeep Wrangler and I like the car, but I think that the interior of the car is kinda cheap.Does anyone have any suggestions to what kind of car is a good buy for this amount?
Thanks!
