Hi and good morning, as my passion for exotics is getting higher waves and I am looking for a comfortable long-distance car with lots of space and good seats (two-time intervertebral disc incident!), I noticed the R-Class in the last few days. To choose from a 2008 model year in long version with the 350 petrol (I hate diesel!). What must be considered fundamentally with this model? What about the rust susceptibility (relative to the ML series). Technical reliability? in conjunction with the 7-speed automatic drive? Would I be very happy about tips! Martin
