With one exception (and even that - the M5 it's marginal) their entire range is anything but a "drivers car" The rear wheel drive thing is just a throwback and pure misinformation so they can sell old powertrains on "new" models. A more dull, overpriced, over hyped range of vehicles you would struggle to find (unless you just happened to visit the Mercedes showroom)
Years ago buying German meant buying a quality build, even if they knew (and still know) f*ck all about suspension dynamics. Nowadays all you are buying is a badge stuck on a cheap assembly of bits - but you still get buyers with more money than sense buying them.
