honestly, i wouldn't mind having one of those little monster miata's with a 5.0/5 speed. i'd put a super quiet exhaust in it and keep it looking as stock as possible but with bigger meats front and rear, just to scare the guys with the vettes and camaros and even some of the late model mustang guys around here.
the most fun i've ever had driving or riding in any kind of car was my best friends old 78 280-Z 2+2 with a built 350 and a turbo 350 trans with a stall convertor, couldn't get that car to do a burnout to save it life...it would push the front tires along the street doing nothing but flat spotting them...AWESOME!!!!! but nail it coming onto a freeway on ramp and it would give you all the smoke you ever wanted to see and doing it sideways the whole time!!!!!! yeah!!!!! that was some cool stuff.
you could be driving along in this thing doing 70 mph and stomp the angry pedal to the mat and feel the ass end of the car scoot over to the left about 5 five feet and about 1 second of watching the car next to you slowly get his nose in front of you then all of a sudden he's about 10 cars behind you in the blink of an eye.
the kicker of the whole deal was rode, drove and handled exactly like his other 77 280-z 2+2 that was bone stock, except that the 350z, as we called it, vibrated and shook a little more than the stock one. they could even have been mistaken for the same car except for the wheels and tires and the 350z was 2 tone brown and gold and the stock one was just gold.
his car was not really loud but you could tell that it wasn't a stock Z real easy, even with 4 brand new mufflers, the front 2 were like 28" long and the 2 behind the rear well where the stock muffler would normally go were about 12" long, now we're talking 40" of muffler on each cylinder bank and it was still loud and unruly enough to know that it wasn't a six banger in that car anymore. we tried different things to make it sound less like what it really was and the 4 glasspacks were the best we could come up with, that would fit under the car.
