i was gonna tell you that celica isnt as fast as a bullet or not as fast as it looks. now that i found out that you got a matrix, the whole story is changed, to worst. ur mini-mini soccer dad van isnt a v6 and doesnt have enough torque to keep up mr. rotary. rx7 has the best rotary in it most probably, and you know how powerful these could get with a few mods. id say put ur money where ur mouth is and swallow it so you wont lose it.
seriously, thats too much of a risk. i'd rather go gamble with that money than race an rx7 unless you got a supra with a matrix badge or something trickier
