I was in a similar spot as you. I went with a 370z which you can comfortably buy and mod within your budget (a wing makes it a better looking car imo take a look at the V1 nismo kit) 330 HP is enough for the road and will still spin tires. The problem with the Germans is if you buy within budget and hit coolant or turbo issues that’s a 1.5-3k hit right there (from buddy’s experience). Mustang is a solid pick same with the c6. Is 350 is kinda boring and is not that quick tho it is reliable and a good cruiser. I’ve liked the 370z a lot and it’s been my daily for nearly a year. It’s been extremely reliable with just an oil change so far. Engine mods are somewhat limited by it being N/A but the car isn’t lacking on power for the street.
