I also enjoyed the article. The only piece that irked me a bit was the GT-R Techtonics by Eric Tingwall.The "Execution" piece should be accurate, but it's not.There are thing that can slide as they are somewhat accurate: 100% of the torque to the rear wheels (in fact it's 98%, but that's nitpicking).The main egregious statements are:"Hydraulically controlled multiplate clutch". It's actually an Electro-Magnetic controlled center diff (GKN's EMCD).Also, "An electronically controlled LSD sits between the rear wheels". Also inaccurate, while there is a VCD traction system in ATTESA, the rear diff is a mechanically passive 1.5way LSD, a GKN Driveline SuperLSD if I'm not mistaken.. what's certain is it's not electronically controlled like the R34 V Spec was.

QUOTE:"Shifting is another issue, as the gas and brake pedals are poorly spaced for quick blips down into second gear and the beefy shifter makes it easy to miss the change back into third. For this reason, it's best to stay in third the entire run. And that's just fine by the brawny V-8. Even with the granny shifting, the Vette manages the second fastest lap of the group. "Given enough time, I could probably get the Z06 to lap fastest, but the GT-R's computers make it easy to get great times right out of the box," Cammisa notes."Wow, maybe you should find some full-grown men to test the cars for you....

I enjoyed the article, although the Evora would not have been my choice for the British entrant. Maybe the Jag or Aston would have exceeded the price limit. If I were in the market, my first choice is the Z06 Carbon with the Porsche a close second (I'd take the Porsche over a regular Z06),the GTR third and the Evora fourth. Honestly, I'd be happy with any of them.
