Fifty years ago (1968-1971) in South Carolina I had the pleasure of owning an XK150 OTS (831898) in GM Ermine White lacquer with a red interior, 4 speed without overdrive.
Enhancements included stainless steel battery boxes in each front wing, accessed through Mercedes 300SL-like louvers on each side, forward of where the cockpit fresh air vents had been.
It also had engine-turned stainless steel threshold covers on each side.
I’ve been trying for years to find out what became of it - initially I heard it might have gone to Michigan.
Anybody know?
