I'm surprised anyone repairs some of these very complex Mercedes !
Just watched on YouTube a Video on Dismantle of a V 6 Twin Turbo
Took an Hour with an Impact Gun and a "Crow Bar" Cost of a repair to a Bent Con Rod ...$20,000 US $ Caused by Water in the Cylinder.
Car off the Road a Week ..a Month ? Worth repairing ?? a good question. For some People it may be just Pocket Money..
I have often thought that for the Manufacturers for these offerings it is just to mop up surplus Cash, that is hanging around, via the Power of adverting, targeting the vanity of some People.
