Never heard of the Mercedes-Maybach G650 Landaulet? Only 99 were scheduled to be built, and chances are you didn't get one. The hefty price tag adds a massive amount of leg and headroom, heated and cooled cup holders, and a privacy partition. A biturbo V12 6.0-liter engine is pushing out 630 horsepower and 737 pound-feet of torque powers the rig.
