My car history has been a crazy ride of performance cars since the very day I passed my driving test. Since then at s rough count I reckon I've owned around 2500 bhp of performance cars,including 8 Impreza's,3 evo's,2 M3's and a host of other wacky wagons along the way lol.
Here's some of my old fleet..
