 The overall interior experience is great, for the two people in the front seats. The people in the rear are left with nothing better than the backseat of a Toyota carolla. I really wish that for the extra money you pay for a Mercedes compared to other German auto makers, you could get better optional features for the rear seats, such as heated rear seats or maybe even three zone climate control. The Bmw 3 series offers the option of heated rear seats, and Audi A4 offers both heated rear seats and three zone climate control. I don't know what's taking Mercedes so long to get with the program. The other crazy thing is, all of these options are available on the c class in Europe! I think that it would be beneficial for Mercedes to add these options to the c class AS WELL AS THE E CLASS. The e class has this same exact issue. It would be nice if Mercedes added these, especially for people who live in places where it gets cold.
