Hopefully I'm not being rude by asking questions first thing, but I deemed it a bit necessary because of my situation

So I'm turning 20 and just departed with my old car, which was nice, and fast; But it wasn't really a very sporty or attractive car by any means. So I've recently taken an interest in Audis as I've heard good things about their really strong AWD drive trains. But I'm very unfamiliar with the lineup and could use some help choosing something I won't regret buying later. And by that I mean..

-I only have a budget of a max 14k, so this makes me wonder if I could even afford/ find a reliable car in this price range?
-I like making my cars faster. So what car has the best/ most durable drivetrain to start out with?
-Also going along with the above question^^^Which is the best performance to dollar model you can buy in my price range?

Thanks for looking, all the help I can get is really appreciated.

Cheers!
