I shove off some time and got pretty close to Taz. My time was 1:28:903.
As for a favored car/track combination that could be used to beat Wobbly, I don't think anyone has beaten or can beat his combination of beer and a gamepad. :D We could have a Ferrari F40 challenge on some track, and as long as no one is using any assists, I would have a good chance to beat the competition... But maybe we should start the challenges with easier cars and progress towards the most powerful, hard-to-tame beasts.
KTM X-Bow R on Vallenlunga club sounds good to me, although I don't remember it having that much straight track, as it's a pretty short one. The game is on next week!
