SPO1457—Zinc Yellow/Diamond Black LeMans stripes. This one-owner beauty is (at the same time) rip-snorting fast and easy to manage on the street. The car was purchased from and completely set up by famed Olthoff Racing in Mount Ulla, North Carolina. Bob Olthoff delivered the car to my home on Monday, June 23, 2003.

Pampered and never tracked or in the rain. She has logged under 12,000 miles [>19,000 km] and has always been housed in a climate-controlled garage.

Outer wheel bands, spinners and sidepipes have been comprehensively hand polished. They look really nice.

Unfortunately, a couple of health issues that accompany advancing age are signaling that it’s time for another owner to charm this “pet snake”.
