Only for fun or vacation, Audi TT:
Turbo kit + chiptuning = from 180hp up to 240hp
And this for every day - a Smart, a very funny car for the city (ask tribal, he drived it on our GTG in Cologne ):
Chiptuning = from 54hp up to 78hp
BTW, can someone source a NYPD or LAPD (or from any other Police department) emblem for my Smart? I was searchin for it here in germany, but I could not find it. 30X30cm would be perfect!
