I think I already made the choice. If I could only have one I would pick the ZR1. In 2007 I chose a Z06 over the Ford GT and a Viper Coupe. To me the Ford is a better investment, better looking, much more exclusive and maybe slightly better performance than the Z06. I chose the Z06 because it is much more user friendly. I can use it as a daily driver. I took it on a 6,700 mile trip and got 25.5 MPG. Drove it 840 miles one day. I'm 6'6" and find it more comfortable on a long drive than our Lexus LS430. I don't fit in a stock GT but from what I read it could be altered to fit me for about $1,500. The biggest problem for me is that the Ford GT has no storage. You must also be careful where you park it because you can't open the door if someone parks next to you.

As far as the Viper ACR being faster than the ZR1 at the Nurburgring it's basically a race prepared Viper. It runs DOT competition tires where the ZR1 uses runflats.
