But then, when did anyone ask about R5's?
Any car you modify enough will be fast. My neighbour's modified G40 is so quick there's nothing on the road he's raced that has beat him. Ok, that doesn't mean anything, but then equally he wouldn't be scared of racing an Uno Turbo. He'd beat one, easily.
0-60 is useless anyway. Let's talk 0-100mph, 1/4 mile and 1 km sprint's.
