Garriott, aside from being a rich, famous games developer is also the son of Owen K Garriott who flew in Skylab in 1973 (oddly just after Lunokhod-2 blew up) and again in 1983 on Spacelab-1.
Garriott Jr was also one of the very few space tourists to visit the International Space Station (in 2008), making him the first second generation American astronaut.
So, Garriott owned a lunar rover, but he didn't really know where it was. Incidentally, he also owns a genuine Russian Sputnik which was 'smuggled' into the US as 'salad bowls.'
Roll forward to yesterday and to researchers at The University of Western Ontario (UWO).
Earlier this week, NASA released a slew of images from the Lunar Reconnaissance Orbiter and Phil Stooke of UWO who recently published "The International Atlas of Lunar Exploration" seized upon the LRO images to search for the rover.
In less than 24 hours it was found.
