Estimate on car insurance? (male, college age)?

-im curious as to what my rates would be like, and nowhere online will give me an estimate.

im 19, in Los Angeles, going to UCLA. My gpa is a 3.95 and im on the deans list. Never been in an accident. Say i was looking at a used Audi TT with 50000 miles on it from 02. What would I pay? 3k per year? 5k per year? just a ballpark number would help a LOT
