Impressed by the modest costs of MB servicing in the USA.
My MB service costs were around GBP400/year. If the car needed pads and discs it could be 2x or 3x that. I don't think that in any of the many years of MB ownership I had that I spent less than £500 per year on service excluding tyres, wipers, and bulbs. As for + ~GBP10 for unnecessary windscreen washer fluid refills... Still, the never-needed but reassuring Mobilo warranty/roadside assistance was included.
Given the price of the Tesla, the annual maintenance cost of GBP450 to GBP825 seems OK to me despite the 'less to go wrong' type claims. Plus, the service interval for MBs was 10,000 miles or 1 year. It rather disappointed me to get the COMAND alerts at 8,000 miles with the telephone call all cued up waiting for me to press 'dial'. Having said that, I'm nearly half way through to that with the Tesla after a couple of months. It's just nicer to be in and drive so I use it for more work journeys and it gets used for all family journeys.
