im assuming you have seen the 458 in the metal ?
they are sex on 4 wheels
comparativly , the mclaren has futuristic lines that look bland
performance wise there isnt a comparison , the mclaren should be faster on the track & sounds like it could be eaiser to push on the road
the 458 appeals to me in that its NA , so the powerband is honest tuned HP (highest "mass produced" HP per Liter), & its great balance could mean its more of a pure drivers car
ironically what the original F1 was designed for
