My B Class had to visit the doctors for some warranty work and MB managed to send the wrong parts. So, a phone call from the dealer and I was told they had a courtesy for me. Well, it is an R Class E350 L Cdi 1600 miles on the clock, what a beauty. Absolutely fabulous perforrmance, but I guess compared to my B it would be surprisingly doing high 20's per gallon mixed driving, loads of space, but I think that is down to the long wheel base. However £57k is a little steep for me, considering the depreciation of them. I would certainly consider owning one when time comes to change.
