I should be more clear, I sprint my car. good fun not too expensive ,and good dy out. but it's one of those things I guess, that as time goes on, and you look fore more speed and quicker times because they no longer fall, you look at the car and say how do I make this go around faster? more power, better brakes? or improve the suspension or swap for a better car,or better driver. I have done most things to the car, I'm stuck with the driver though(me). the power is the expensive bit. so do I carry on with the current car or upgrade? (money permitting of course)
