I just watched top gear last night when they were testing the GT500, (not sure how old this episode was).
To sum it up; they loved the power. hated the handling and they said it no real heart to it (if u know what i mean, sorry i cant remember the word they used).
With the M3 (like someone else said above) its a classy car that has much more purposes then a Mustang!
