That was the biggest problem with it, can't keep the rear wheels hooked up! It will break loose through the first 4 gears if not corrected for and it has a tendency to drift to the side a bit when they light up. Love the horsepower but I think the SL 55 is more usable. Have a CLK 550 convertible and an ML 63 right now. The SL 65 was a stretch for me so I tend to play in the lower leagues, unlike yourself!! Love the Atom by the way!
