there's lots of good performance vehicles domestic and import from the 80's. just from the g bodies you have the hurst/olds, turbo buicks, monte ss and aerocoupe.
84-85 mustang gt's and the later mass air cars. svo mustang and turbo coupe thunderbirds. crown vic police cars had a 2 barrel and 351's.
mopar had the various turbo shelby cars
chevy had the 350's in the camaro and the corvette started getting some balls back to it.
nissan had the 280zx and first gen 300zx turbos, 2 generations of mazda rx7's(GSL-SE model in the first gen and turbos in the 2nd), toyata supra turbo.
bmw had some decent m cars and a lots of different 3 series models(325is, 325ix)
almost all the cars can be had for reasonable prices still and most have decent aftermarkets or can be hopped up using normal hop up techniques. the 80s was great. the automotive industry finally came out of the emission dark ages and finally saw the advent of electronic fuel injection in almost all vehicles to help with performance, emmissions and driveability.
the suv craze killed most sports and muscle cars in the 90's but right now we are in another sports car and horsepower era with the import and domestic factories turning out cars with crazy amounts of horsepower and features.
