A good friend of mine has a motorsport escos with 21k on the clock, big brakes (bells and rotors) 19" rims, 400bhp and I think he wanted about £18-20k for it a while back, neadless to say it is still on his drive and im pretty sure he has no intention on selling it now.
He knows his cars and I pressume this isd a tad over priced? I really don'tknow much about these cars in the sense of what they sell for but this may give you an idea.
