C8 failed Inspection
Took my C8 to get inspection and it failed because of evap and O2 sensor not ready. No codes. Anyone else have this problem?

My two cent comment.
How many miles on the Vette?
Was the battery recently disconnect (or run down)?
I have read before one needs to drive the car a hundred or two miles to set the smog data in the Vette's smog setup computer.
Further, there may be a specific GM driving scenario/ setup/ instructions, such as varying rpm for "x" number of miles, that can be followed.
Anyway, good luck.

I'm assuming the OP purchased his car out of state and now has to get a smog check to get it registered. Purchasing a new car from an in-state and not having to get it inspected is standard.
The car's computer is looking for some specific driving conditions to be met before it knows everything is OK and is ready for an inspection. You can Google GM Drive Cycle for more information. So, depending on how the car is driven, it can take hundreds of miles before it is ready.

I’m buying my car from a local dealer, but having it delivered at the museum. I would assume that my local dealer would be the dealer of record. VA doesn’t require an emission test on new cars for the first 3 years, so I should be OK.

It is standard on all cars and pretty annoying. The evap system requires a really goofy and specific sequence of the car being at certain speeds for a certain period of time.
I struggled getting the monitors set on BMWs, Hondas, and other cars after ECU resets. Huge PITA.
