I already bought a big rooftopspoiler, and am colourcoding my car to the max.
It's already nice now, but not 'perfect', really shiny!
It's a 5 GTS, with std 68 bhp, but modified to 83 bhp, with new Weber carb 32 DRT
bolt-on K&N filter, and huge/load PECO BB4 exhaust system
Splitifre sparkplug leads and more...
Maybe nitrous-oxide in the future (then my 5 will be faster than a 5 GTT)
