i havent owned much cars since I'm 16, and still on my L's
The fastest car i own would be my new pride and joy, my Mazda RX7 S2 (don't worry, i still have the ke10 :) )
sorry for crappy pic, i only just bought it, not overly modded, but can definately get to 80k's with no worries :)
has hi-flow everything, 4 inch Cannon muffler, extractors, a few other things
