Just as cheap, but still not an excuse for Mercedes

Oh for crying out loud Gian... Are you trying to pull a Levi here?

Come on Martin, the long term durability it's not the same. The double A arm has 4 big anchor points whereas the McPherson has one (not taking in count the shock absorbers, etc) Hit a pothole, curb, etc with a McPherson and it's much more probable that you're going to have a bend arm than the double A arm configuration.
And it's also suposed that A arms have better ride/handling characteristics, no camber change, etc, but that's not my point, to be honest. I't's more about durability. After all, you can find McPherson in all cheap cars, where premium/serious off road tend to use A arms.
Nope Kowalski mate, is more of pulling a Naas @Human here. I'm just tired and deluded of seeing premium manufacturers cutting corners here and there. It's not just Mercedes, but everyone that comes to my mind, and in every business: Bosch, Makita, Braun, Tissot, DeLonghi and ad infinitum.
I guess it just the rules of the game, nowadays. I'm off to get a drink.

That's not entirely true.
1. In any case, you have bushings that absorb the forces and when they are not enough, the first thing to bend is the rim, usually. If for some reason the rim survives, the lower wishbone from a double A arm setup will take nearly as much of the hit as the single wishbone of a McPherson setup would take.
2. You can still play with every angle you want, by having two different wishbones. Think of how would the wheel angles change, if you had a smaller upper wishbone
3. One "benefit" of the double A-arm suspension setup is that the steering angle is connected to the upper part of the wheel hub, where it connects with the upper wishbone. The fact that the lower wishbone will take most of the hits from the pothole and all other road surface irregularities means that your steering feedback will be heavily filtered out.

Giannis, I'm not saying the McPherson is an absolut crap, but is indeed a simpler, cheaper, less stressable system, compared to double wishbones. It's like half a wishbone (McPherson) doing the same work of two full wishbones..... Not a bad system per sè, but I expect the real McCoy, from Mercedes (and after all, it's what they used to do....)
