On the other hand, I've had vicarious experience of three Mercedes sedans through people I've known, and they've all three been disasters. I guy at work has a Porsche, and it started honking the horn when he stepped on the brake. They told him the part had to come from Germany - in several weeks - and would cost about 2k to fix, so he simply disconnected the horn at zero cost. German engineering, you know.
I can only imagine the financial rape that would occur should your Maybach start honking the horn when you stepped on the brake.
