not to stray from random even farther (or to go all "Mustang" on it) but...from the web:
The most sought after Corvette ever to roll off the assembly line is the ultra-rare ZL1. According to GM production records only two were built. Its engine option added over $4700 to the cost of a standard car. The ZL1 motor incorporated a specially reinforced all-aluminum 427 block and heads, with a radical solid lifter cam and a Holley four-barrel 'double pumper' carburetor. These cars were rumored to have 700 hp and be capable of 200 mph. This car was originally ordered specially for racing by John Maker of Leechburg, PA through the office of Grady Davis of Gulf Oil. It was raced for four years in drag racing events. The current owner purchased it from Mr. Maker in 2007. The odometer reads just over 3,000 original miles. It is in original condition except for a repaint (in the original color).
