 Having moved up from an E500 that I thought was a good ride, this is sheer driving bliss. The quietness, feeling of solidity, lush interior ambiance, smart Euro styling, responsiveness, fore and aft roominess all combine for a memorable driving experience. Although my choice is not heavily optioned, the long list of standard features adequately satisfies my convenience and comfort wants. The paddle shifter capability is of dubious value for my driving habits and they inadvertently get bumped on occasion. I plan for this car to be a long term keeper and knowing that MB maintenance cost is expensive, I opted for the extended warranty.
