130k stateside looks like. And for what looks like 5mph top speed difference I say hell yeah. I suspect the GT 500 won't deliver it's 200mph alleged track speed either, or beat the GT3's 3.3 0-60 speed.
Well I hope not.  The Shelby is half the price of that car.  BTW, I am putting about $4000 in mods on my car which will yield great traction and about 150 wheel HP.  I don't think anyone can do that in that already maxed out Porsche.  
FTR, By no means am I knocking the Porsche(s) -  great cars.  I am just saying I get a hell of lot more performance for my money in a Shelby GT500.  And oh BTW, I like Mustangs
