And the strange thing is, tuning your car is a bad investment, but the tuning parts themselves are fine investments (better than a new car probably).
I mean a 5 year old sc kit or LSD or BBK will often sell above half its original value (msrp prices seem to go up too in that time), whereas the car probably wont
Whenever you see a modified car for sale, first reaction is probably "how much for the bbk alone?"
The biggest problem obviously is: all enthousiasts already have the car, but not the hop up parts...
