2007 Mercedes-Benz S-Class S550 4dr Sedan (5.5L 8cyl 7A)
We have had our 2007 S550 for nearly one month and find it an excellent vehicle. Both interior and exterior are well thought out and everything works as advertised. It cruises most happily at 80 mph (at 2000 rpm) while getting 25 mpg on premium fuel. A bit more thirsty at speeds below 55 mph. We are quite pleased with our purchase.
Integrated telephone system using cell phone. Voice commands that work; 7 speed trans.; strong, very adequate 8 cyl. engine race tested for 10 yrs.
Slight hesitation when accelerating sharply from idle. Might need adjustment.
