Most American brand ECU's don't bother with this feature. It's not like we're spending hours at a time on the Autobahn at Vmax.

Given your screen name, you should already know what to look for with regards to if the car has been used or abused at the track. The car isn't super easy on tires and brakes, so if it's still on the original tires with barely touched shoulder wear at 8k, then it's led an easy life. Brake rotors w/out any heat-checking means it hasn't been tracked, or tracked so lightly it's of no concern. As for a money shift, that by definition would require a new engine. The Chevy dealer should be able to show you service history with a VIN lookup.

If you want to avoid all that, then buying new is a sure thing on getting an unmolested car.
