[7] It was announced on May 8, 2015, that the Larry H. Miller Group of Companies would not renew the lease on the land in Tooele County, Utah on which the park sits.

[8] According to local news sources, as of July 17, 2015, there were several offers being considered by the Tooele County commissioners that would provide for the facility to continue operation.

[9] On October 13, 2015, Tooele County voted to approve the sale of Miller Motorsports Park to Mitime Investment and Development Group (a subsidiary of Chinese car manufacturer Geely) for $20 million.

[10] On December 17, 2015, an order filed in the 3rd District Court vacated the sale of Miller Motorsports Park to Mitime Investment and Development Group, saying Tooele County shortchanged another bidder by unlawfully selling the property at a price significantly below fair market value.

In May 2016, there were pending legal challenges to the sale, but the facility opened for business as the Utah Motorsports Campus.
