I road with Michael Curcio on the dragstrip at Indianapolis Raceway Park. I had to roll the window up to keep the smoke from the tires out. What awesome acceleration!
I haven't had so much fun since college days when, with my suitemates, we'd cruise the back roads at 145 mph in a GTO, a 396 SS, and a Corvette with redline tires - a set was good for about 3,000 mi.
Cruising at 60 mph and nail the Kleeman CLK 55 ... you are glued to the seat back and the car just flies and it is civilized like you'd expect from a Mercedes.
