It's difficult to justify on a car over 5+ years old if you don't get a gearbox service.
I'm thinking of stopping mine (£39pm); for the current B service @ 137k miles, due in a about 10 days, they're told me they're only going to do the oil and oil filter and look around and give me a report...
Even though the car hasn't had filters and brake fluids changed in ages, they just go off what the ESS says like robots, instead of actually LOOKING at the history and deciding what's required. What's weird is that in the past, the filters have been changed more regularly according to the service sheets, so I thought I'd be due getting brake fluid, air filters, fuel filter, and cabin filters changed and following the past schedule.
MB seem to think it's okay that air filters aren't changed for 50,000 miles - I opened them up and have had to clean them out a few times as they're so bad. I'm quite sure that the cabin filter was not really changed in late 2017 as the state of it when I looked at it in early 2019 and cleaned it recently, was truly shocking.
When I started the service plan, I was told a gearbox service would be included (by clueless staff members), but it turns out they were wrong. So the value for me has plummeted.
So, this year I've paid £468 for a £12 oil filter, about £40 of oil, and a guy to look around under my car with a torch for about few minutes. And those are prices *I* could get the genuine MB parts for. Great!
Yes you get mobilo, but be aware they will only take you to a MB dealer so be prepared to pay MB prices. I am also going to get a hire car off them for the day too, but I'd personally rather is was simply cheaper - or do the actual servicing the car needs. Hopefully the experience will be 'nice' at least, and I'm taking it to brooklands.
I think the real question is - how old is your car, what's it worth, and does keeping a full MB dealer service history actually add value to the car?
One caveat is that if it includes a gearbox service, then it's definitely worth it.
Sorry, rant/steam of consciousness over!
