How much would it cost to get a TVR over in the States?
Oh, you couldn't even get it done could you...
Would surely be a lot more than the Z06.
I've only seen one Mag list a Z06 at 4 seconds, and they also listed it as 12.3 1/4 Mile...so I wouldn't put too much stock in that, as they are the same people who say Camaro's were 14 second cars...
Personally, I think there is too much crap in the Z06 interior, Id like to see it stripped out a little more, lighter seats...and though it would raise the cost, some carbon fiber work on the dash and whatnot...
Drop that weight under 3000lbs...
Oh, last I checked, the Z06 ran a 7'43 at the Nurburgring, unless it has officially been announced that the Blue Devil, which is still just a rumor, was the one that set that time.
So yeah, it's faster than an M3, and then some.
