Or the flip side of the lesson, prepare to drop your keys out of the the Lear jet if you get a modern ultra luxury car...
You'd have to sell the Lear just to afford maintenance on a used Maybach. Upside to selling the jet is no more lost keys.
I am curious about that as well. The drivetrain is 'basic' benz TT V12. Most the electrics are S class derived. I would venture it costs exactly as much as your typical S600 (W220) as a result. The only parts more pricey would likely be the body panels (insurance), and model specific motors/actuators for the rear seats.
Just because the parts are basically the same does not necessarily mean that they will CHARGE you the same.
