This one qualifies as the opposite as my other submittal. I can visualize a 1972 Lincoln Mark IV (pre federally mandated 5 mph bumpers) as a starting point. I checked out a nice example at the Auburn Indiana (Auburn-Cord-Duesenberg) cruise-in this summer which got me thinking. This is a car that screams for a 4-inch chop of the roof. Lower the car 2 inches, fill the wheelwells with some wide rubber and paint it semi-flat black. There is currently a Mark 4 on E-bay that would be a good start in the right direction.
