I'd still prefer a straight line car than a corner carver anyday. I'd rather have the advantage where I can use it anywhere on any road where 99% of driving will take place, rather than making excuses, "Well if we were at the Autocross..." . GT500 in my book, it's faster and more powerful.
If I wanted a corner carver I'd build a kickass 240 for half the money and smoke both cars on the track.
But each to their own! If it wasn't for this rivalry these cars wouldn't exsist today.
