After nine years I'm changing my beloved 2009 Merc E220 as it's starting to cost money. Long legs mean I need my seat fairly well back for my 15-18k town and M-way miles each year. I want something fairly solid and good build quality, four-door, space in the back for frequent four-up journeys, relatively economical but with a bit of poke and flexibility in the engine, cruise control, parking sensors and acceptable maintenance costs, to keep for another five to seven years. Am I expecting too much or could you suggest please what might be worth looking at? I have £20-25K to spend.
