A 355 GTB would make a great street and track car. In fact if you can find a 95 Challenge car, they have titles, so can be driven on the street.
Aftermarket wheels, brakes, tires, safety gear, etc are plentiful.
The best sounding cars on Youtube are 355s with Capistro stage 3 exhausts.
I also like the TR variants, but see them more of a highway GT car.
