Funny you say that. The longest I driven was about 12 hr but still, very confortable, no soreness at all. In my now defunct DD on the other hand, a 2001 Grand Prix GT (busted CV axle), I can't drive 1.5 to 2 hours without getting back pains or even worse, travel butt.
Best time: 14.690 @ 94.18MPH '91 Black 2+2 N/A
