Awesome game a little slow on network to challenge other players. You should add the Toyota Celica, Mitsubishi Eclipse, VW Jetta TDI, Nissan 280Z for tier 1. For tier 2 it should be a Lexus is 250 or 350, Kia K5, Dodge neon srt4 and For tier 3 Ford f150 lightning, 99 Dodge Dakota R/T, and a Mitsubishi 3000gt or Dodge stealth R/T either should be awd, and Nissan 300ZX. You should also make it to be able to do engine swaps as well like if you have a classic cars and make it cheaper.
