Had a 1988 300CE for many years then chopped it in for a Chrysler Voyager when twin Boys were born and we already had a 3 year old LOL All grown up now and my Wife has a nice MK1 TT 3.2 VR6 which is lovely but we could do with a 4 seater convertible - There seem to be a lot of Nice looking 4th geration W212 e Class convertibles on the market 2009 - 2016 . Question is which is best for mainly local milage with occasional long trips - looks like the cars are all Diesel and I'm fed up with DPF and other Engine related problems like I had with a Q7 Diesel not long ago. What model year and spec is likely to be less troublesome and what should I look for buying this model? E400 is atractive but a lot more money? Thanks in Advance for any tips
