Sprint Cup SponsorshipEdit

Best Buy began its foray into sponsorship in 2005, when it was the co-sponsor with Netzero on the #0 Haas CNC Racing Chevy. The Best Buy sponsorship made its full debut at Dover in the fall, as Mike Bliss crashed that car early.

In 2006, Haas CNC announced Best Buy would sponsor the car in the majority of the races. The car would be renamed '66' in honor of Best Buy's fourtieth anniversary, as the company was founded in 1966. SanDisk, a MP3 maker and large partner in Best Buy, is on the quarter-panels.
