Dude your 16 you dont need a 12,13,14,15 sec car Enjoy the fact you have a solid decent looking car
When i was 16 I had a 81 nonda with 210k on it one speaker am/fm radio
Barely ran
What the hell is wrong with the youth of today so damn entitled to have it all
Just be happy you have a solid running car , do small mods to it and when your old enough for a big boy job MOD it
Im 30 i have been there done that and can promise you that supra will cause more bad then good and when you blow it up or wreck it What will you do
