When you start with the ultimate driver’s luxury car, and then add over five more inches to the wheelbase, what you get is the 2006 BMW 750Li-and even more reason to remain behind the wheel for as long as possible. On top of the excellent performance and luxury found in the 750i, with a 123.1-inch wheelbase, the 750Li offers more legroom for rear- seat occupants, standard 20-way comfort front seats, and chrome roof moldings. The enjoyment provided to the driver of such an extraordinary mode of transport is, ironically, practically immeasurable.
