Power Locks,? 2 KeysThis Mercedes-Benz SL600 Roadster is in excellent overall condition. This is a great value considering this car was over $90,?000 when purchased new. The twin-turbo V12 engine is the star of the show. From a standing start,? the Mercedes SL600 can hurl its 4501-pound bulk to 60 mph in 3.6 seconds. Fed by twin turbos with twin intercoolers,? the SL600's SOHC 36-valve,? 60-degree aluminum V-12 spools up 590 pound-feet of torque,? maintaining that mountainous level from 1800 rpm to 3500 rpm. The five-speed automatic offers a three-mode manumatic function,? just as it does in the SL55,? but with such an abundance of muscle,? augmented by quick throttle response,? it seems superfluous. When the driver wishes to summon haste,? he has only to tramp on the pedal and the V-12 will mash him against the seatback in a flash. Although heavyweight punching power is this car's main purpose,? there's more to the SL600 than shrinking the time between points A and B. Mercedes-Benz's active-body-control system keeps cornering attitudes level,? the steering is quick (albeit not particularly tactile) at 2.6 turns lock-to-lock,? there's adequate grip pushing .88 Gs sideways,? and decent braking performance - 178 feet from 70 mph.
