The other part is apparently a desire to be excellent, and that part, they have nailed: you can register to win, win no purchase necessary, either a 2013 Corvette 427 Convertible Collector's Edition and a trip to the 2013 Le Mans 24-hour or a 2013 Camaro ZL1 and a trip to the 2013 Indy 500.
Only U.S. residents are eligible, and you must be 18 to enter, but beyond that, the barrier to entry is nil.
If you're in the mood for a free Corvette, however, you'd better hurry--the contest ends tomorrow, June 20, at midnight Eastern time. Those angling for a gratis ZL1 have until July 9 to enter.
To enter, all you have to do is fill in your name, address, and a few questions about Chevy vehicles you'd "like to learn more about," then opt in or out of sharing your contact info with a few other outlets. An invitation for spam? Perhaps, but the reward could well be worth it.
To register for either contest, hit up the Team Chevy Facebook page.
