1970 COPO Z28?

[owners2]

The best way to tell if it's a true COPO 9796 is if you can get the build sheet. If this isn't possible (b/c not all cars came w/ build sheets) you need to check the mounting holes to the rear spoiler to see if its perfectly punched out, (anyone w/ a drill can install a spoiler). Also, I would speak with the original owner, if possible, find out if they special ordered the spoiler. Learn as much as you can because there are many that have different opinions on the exact dates. As for value the car is worth as much as the buyer is willing to pay .
