Here we go again.
The quoted comparison shows cost of maintaining on MB things like Bluetooth, navigation, dual, or quadruple climate zones and hundreds other things the other cars simply don't have. Sure MB mechanics charge per hr a bit more than Ford mechanics (and wash the car after the job), but again -I haven't found yet any Ford parts where Mercedes equivalent would not be cheaper.
I think you live on another planet. Or in your own mind.
Bluetooth? Navigation? Multiple climate zones? We're not in the 1980s anymore. Get out there and look at what all cars
have these days in respect to their standard equipment. In fact MB is at the bottom in respect to a lot of techno goodies (esp the Nav system.) Daimler has had a notorious history (BMW, too) in respect those "things" you mention compared to other brands including Ford (btw, have you been in a modern Ford lately? They also have all those "things."
It was inevitable that there would be the usual responses based on personal experiences. And that is why I included this caveat: "Before anyone lists specific personal experiences as a response, bear in mind that this is comparative only. YMMV, of course."
And the fact remains, that a majority of Mercedes owners do not have the time nor inclination to wrench their own cars. There was a time (and when I had the time; when it was about enjoyment of learning and fixing my own cars), that I wrenched on my Porsches. Of course they were cheaper to own that way, and it saved me money, but owning a Honda was still cheaper.
speaking the world knows that a Mercedes has a higher TCO than many other brands. The TCO of a Mercedes is higher and it's understood throughout the industry. Nothing more nothing less.
I'm not sure why this is so difficult to accept.
It's no big deal, it's just factual analytical data. Dismantle the cars and by parts alone see which brand comes out the most expensive to put back together (by yourself and with your own tools.)
And there's no reason to defend your decision to own a Mercedes and feel comfortable with that ownership. We're not talking about your Mother. It's just a car. Hey, I own the brand, too. But there is a reason the most common questions for new (and current) owners are primarily about warranty extensions and repair costs. And it was the reason for this thread from the onset.
