even a stock M3 that is driven well will give a diablo a run for the money. a reasonably tweaked one will walk all over the lambo on any race track that doesn't have a 2-mile straight. an M coupe (240hp/240lb-ft) can't quite keep up with my lotus (190hp/150lb-ft), although it's really close. blah-blah. it seems your own unfounded opinion is the only 'proof' you require anyway, i just had some time to waste so i replied. have fun torquing out there.
