Hi all thinking of buying a 300c to for longer motorway journeys. I drove one when they were new, but fell for a e class merc instead. So am looking now, but very conscious that most in my range are 2010 or older. Is there a Buyers guide detailing areas to look out for? Or a checklist? I am getting a feel going through the posts, but tbh, there are quite a few topics….almost enough to put me off! are they generally reliable?
