I am suprised that Lexus would include an XLR. It has been compared to the SC (and others) by all the popular mags. It has finished first or second in all comparisions with the SC finishing last or nearly last in all.
As for the tunnel heat, I would expect that they had a very early model or had taken the car apart to study it and did not put it back properly. There was one complaint of heat on this forum. However, I have driven mine for over four hours on 90+ degree days without any noticible heat buildup. Actually, cool to the touch. I personally think Lexus would give there right arm to be able to build a car of this quality in such a short time frame. It goes to show just how great a job the folks at chevy did with the c5/c6 chasis.
