I'm not in any way saying that a 996 is not a very good car but I'm sure there are plenty of cossies out there that would do well against them.
I had a play not long ago with a GT3 and he couldn't get past me and my car sure as hell didn't cost me a quarter of what one of those costs to build.
If a 996 is so 'affordable' compared to building a 500 bhp saph, then why aren't more people doing it?
