Hi all I'm constantly told that having a C63 with full MBSH is utopia rather than a full service history from an indie as resale will be worth more. As its coming up to service time, I've had quotes from the Merc website for a service B at just over 20K miles and depending on the location of the dealership it varies from £800 odd in Guildford to over a grand in Croydon. (Car is 2014 6.2L not new turbo) When you look at the service brake down, the only thing they are changing is oil, and key fob batteries - everything else is checks! Is it really necessary to maintain these by going to a main dealer, that will probably have a junior mechanic working on it anyway just to keep the resale value up? I fully accept the prestige part, and I love my car to pieces particularly as I'm lucky enough to have a 507 edition, but like everyone else, I don't like being stitched up! Thoughts?!
