Again im suprised with old M3 peformance.
Its 5 yeas older, based on massive producion car, and its head to head with the Porsche brand new (at the time) mid engine 2 seater.
I have no doubt that Cayman S is overall a better tack toy and sports machine, but its funny how close M3 E46 is behind.
Those are diffrent cars to diffrent tasks, but, in real life - it would be hard to feel the speed diffrence. And M3 is propably more user friendly with more space to laguage.
