You dont want a Mustang SVO....or a T-bird Turbo coupe
You really dont want a Volvo, or a BMW, cause under $4500 they're gonna be a piece of old crap
Any 90-96 300ZX for $4500 has got to be in rough shape or have problems. Also, 300ZX's are PIGS....they weigh a TON and are therefore not as fast as you think they would be.
I think your best bet for that kinda cash is gonna be a 87-91 Supra Turbo:
Turbo inline 6-cyl rated at 220 hp
Front Engine/Rear-wheel drive
Sporty looking car (unlike those old-ass volvos and BMWs)
Lots of tuning potential down the road
Just my advice/opinions
