You can always look into a good used 370. I'm just saying....

As I usually mention in threads like these. A used 350z or G35 would be best. Cheaper priced and lots of fun to drive. Tons of modding options available too and these cars are reliable.

You could get an used early 350Z to start with until you can afford a 370Z.

If your parents are willing to co-sign for you, you can be bumped up a tier if your parents have great credit.

Insurance is gonna be nuts though, unless you put it under your parents name.

If you're trying to do this by yourself with no assistance, it would be tough.
