Awesome car, looks badass with those gloss black wheels, congratulations The options you chose are great, too.
As to oil changes, I'm following the 2018 track prep guide that came with the car, and it recommends the first oil change at 500 miles.

I don't use OnStar much, although upon delivery I did purchase a security package that will continue after the trial, but only because it was a good deal for some extra peace of mind about theft and the like.
