I just wouldn't. I mean, I'm not exactly a Merc fan anyway, whenever I drove my mates C class it was just soul destroying (I'd much preferred to drive my 11 year old Passat than his 3 year old Merc. Hopefully his new C250 is a vast improvement). But I did ALMOST buy an E-Class before plumping for the 5 series. But now, with the closest non-AC dealer being a 200+ mile round trip, I couldn't bring myself to do it. I wouldn't want AC servicing my cars, so hooped driving all that way for a service. Not when John Clark are actually pretty decent, and I can get BMW's or Audi's serviced only 20 miles away. And I prefer them two marques anyway.
