I am trying to figure out what model these cars are? http://www.youtube.com/watch?v=6P4qk...eature=related I am NEW to the mercedes family. I currently own 1990 jetta vr6, so im still in the german scene. I am just trying to figure out what model those cars are and the difference in 190e's and 190d's...is it just that one is diesel and one is gas?
