I'm fairly certain my 300D has MB Tex -- seat cushion pattern is different than the leather on my brother's 300SDL. Can't say for sure, though, since I've not bothered to get the window sticker. Spotless in either case, unlike some of the other stuff.

Cost will depend more on age and milage than trim level or engine -- the 603 isn't as common as the 2.5, but I could easily do without the difference in power in trade for the better milage -- I get 30-32 on the highway, would much rather have 35-36!
