After my agreement on my current 2009 C250cdi estate ends I will probably be wanting to keep my next car for a lot longer maybe up to 10 years. I have seen on this site that there are many members running cars 10-20 years old. I would value anyone's opinion on what model/year they would consider a good bet. I have in mind either a C class or E class estate probably but not necessarily diesel. I particularly like the late W211 E class. I hate the bling on the current ones.
