The MMU
In the aviation world, we often speak of the cost of things using AMUs as the measure. As in, "I just spent 3 AMUs on a prop overhaul", or, "Wow, what did that cost you?" "Oh, it was only a couple of AMUs." An AMU is an Aviation Monetary Unit, and is currently defined as $1,000. It's particularly useful when discussing airplane expenses in front of spouses.
Owners of larger Mercedes should probably get their own unit of measure for cost. The MMU (Mercedes Monetary Unit) would be one obvious choice. I suppose the only question is whether $1K is sufficient valuation.
This weekend I'll be throwing about half an MMU worth of parts at mine...

Dale,
I also like the MMU, as derived from the AMU…
I waded into the aviation world representing some Twin Commander owners surprised to find their “bargain” twin prop needed a 150 AMU wing spar replacement. That, and two rich guys litigating over the cost of a Citation (personal jet) windscreen replacement...
As a former Ferrari owner, I know too well the FMU (use whatever acronym you want for that one!). 2 FMU’s for sparkplug wires… just the wires, not the coils. I bought my Ferrari, with only 15K miles from a guy who had spent 30 FMU in the last 500 miles. I can’t imagine why he wanted to sell such a low mileage car???
On the price of MB parts, I haven't had much sticker shock, other than 1 MMU for a V-12 coil pack and 0.5 MMU for ABC hose. On other stuff, there’s aftermarket and used. Which brings up the $1K unit for the MMU.... My recent posts had only 0.007 MMU for a washer pump and 0.008 MMU for a wheel sensor. That may get confusing for the math challenged and, at a minimum, require a calculator for most of us...
I also like the last three numbers on the trunk as the cost of a trip to the shop... Although adjusted for inflation, requires quadrupling… 550 has become 2200….
Also, really appreciate you guys that share repair info here. I try to do my part but haven't needed much help, thankfully, and don’t follow the forum except occasionally.
Here’s a suggestion...
In my Ferrari ownership years, we requested and the moderator put together a “Sticky" for cross-referencing part #'s. For example, I was the first to confirm that a $15 VW thermostat worked even better than the $250 Ferrari V-12 thermostat! (But, that was only 0.25 FMU’s... a pittance.) Point is, none of my cars have seen a repair shop for at least 15 years. Exotic car ownership doesn't have to be expensive. (Did I just call the S-class an “Exotic"? Well maybe the S65...)
Does anyone else think a part cross-reference is useful? Moderator?
