What car should I get next for trade in?

So I have a 2006 ford Mustang gt I got it with 95k bought it for 15k. I've had it 2 years and it's been a money Pitt. Invested alot of parts that go out. It's not even modifications it's stock oem parts. Had it 2 years it has 145k miles now. I'm getting tired of it breaking down. Plus I doubt it will last 200k for the engine. It's broken down 5 times now. Three because the alternator went bad then other 2 was parts just gave out. I like it not going to lie but tired of it breaking down alot. I'm planning on just trading it in for something different. I have a couple cars I've been looking at but wanted to see if anyone has had owned the cars I'm looking at. This will be my dd and take it to the drag strip like once a year. Cars are: 2010 camaro, older m3, challenger rt , Honda s2000, Mitsubishi evolution, nissan 350z or 370z depending price, Subaru wrx from 06 and up. My price point is from 20-25k and want to see what are peoples opinions on these cars. Something that I can rely on and later on do some modifications. I am 21 years old and I'm a mechanic. Living in California. Not looking for fwd.
