That GenIII car is more of a luxury sport car than a fast Supra. This Supra is a porker and is heavy as heck, therefore, it's by far not fast from a dead stop. I used to own a 89 Supra Turbo and the fun is on the freeway. Just boost to pass up on anyone in 5th gear without downshifting. It's used to fun watching those like the little four bangers rice rockets down shifting to keep up. Check out socalsupras.com and supramania.com for more resources. If you want fast then get a GenIV Supra with the twin turbo. It's also a lighter car and plenty of mods available.
P.S. It's also a big gas guzzler. 18mpg on street driving.
