GM’s new commercial features CEO Ed Whitacre walking through an auto plant as he tells us that GM has repaid its government loans five years ahead of schedule. The commercial shows many of the successful cars and trucks in the GM lineup with a heavy dose of Malibu. At one point during Whitacre’s stroll, you can see what we think is a Cyber Gray Corvette ZR1 in the background. Although relegated to the role of extra, we appreciate that Corvette was in the mix, however briefly. Check out the video after the jump.
