My guess is the Porsche driver was inexperienced, judging by all the mid-corner braking and some of his lines. That driver seemed too proud to give the point-by to the Mustang driver (who was obviously more experienced/faster).

looks like Porsche driver was afraid of the twisties

It just shows Experience>Money.... None of them were pushing it really hard though.

im a huge fan of mustangs, however the guy in the porsche must not have been pushing that hard expecally if its a turbo, at the begining the old ass bmw was keeping up in the corners. trust me if i paid 130k for a car i would take it easy to.....
