So I just bought a 2015 Z06, and on the carfax it shows the first oil change being done at 1100 miles. I know the proper spec is to do it after the first 500 miles. Is this something I should be worried about? The car has 4k miles on it.

No. It won't be a problem

All you know is that an oil change was done at 1100 miles. It may not have been the first one.

Either way, it's still good.

Mandatory 500 mile change from GM came out near the end of 2014. I think there were many cars that were over the 500 that got a "late" oil change. It will not kill the car, not an issue. The 500 change was to stop the "burp" of oil into the intake plumbing via the PCV hoses.
