Hi, I have recently sold my 530d sport saloon and want a change. So, I am considering a merc-Benz E320 3.0TD 7G Sport estate but I have no merc experience other than a few vito's.....which haven't been so good. Don't have a huge budget, circa 10k. What are these cars like and what to look for? Thanks in advance. P.s....If anyone needs heating advise...that's my business!
