I had a e-class estate for about 9 years until last year. I loved everything about it apart from, latterly, the rust, the fuel economy and the running costs. I turfed it in for an 08 c-class estate 220 sport. Lovely car, however I really miss the space in the old e-class. Also my parents aren't getting any younger and they find it a bit of a struggle getting in and out. So I'm thinking of going back to an e-class estate. The only things I don't want to compromise on are fuel economy and trim level. I like the COMMAND,heated seats, electric tailgate etc. I'm also prepared to part ex and pay a couple of 000 extra. Any suggestions from you what model/year I should consider?
