Just got back from an AMG GT-S track day at the Thermal raceway near Palm Springs and I was most impressed. Having owned and raced Porsches for many years, and owning a number of AMG's I expected a fast, solid straight-line car. After an afternoon flogging one around the 3 mile track in race mode, I can truthfully say that this car handles both road and track better than any 911 variant. My 997 GT-3 might go around a bit faster (not even sure about that)but on the street, there is no comparison. Sharp turn-in, easily modulated oversteer and monster brakes for the track but superb manners on the street. Mercedes has a winner.
