Thanks to both for the replies. Jim, how much room do you have between the car's front seat and the Century baby seat? The Evenflo Trendsetter On My Way that we currently use is a pretty tight fit in my SD, but your 420SEL has the longer wheelbase, and, presumably, more back seat room.
Our daughter seems very happy riding in the back of my car as well. (I feel quite a bit safer in my Mercedes than in a minivan.) In fact, the slight vibration of the diesel helps put her to sleep
. At night we turn on one of the rear reading lamps so she can see her mother.
