Around $65k gets you a new zl1 1le, that car out of the box will be competitive with gt3s of any generation. But you’ll be driving a camaro, so there’s that.
Cheap (ish) speed used c6 zo6 and mod that car, much better platform to start with than a 370z.
A new mk III TT RS with stage 1 tune and rear sway bar upgrade, fluid and brake pad upgrades, and front camber plates will match new gt3s in performance. The tune puts the car at a 10.9 sec 1/4 mile at 124 mph and the other small upgrades get you the improved handling and braking.
A used gtr is also a good option but mods and maintenance and repairs will be more expensive than a vette or tt rs.
You know the best way to get 1 million dollars right? Start with 10 million and take up racing as a hobby.
