That's pretty low miles, nice.
Things I can think of if you just got it - Supercharger oil change, check the coolant elbows visually to see if they're leaking but plan to put aluminum ones in anyway, LIM (Lower Intake Manifold) gaskets fail on many GM vehicles. There is much to find via google. It might look like a big job and it kinda is, but when you get done you won't be afraid to dive right in again.
Good to see a kid actually care about a vehicle they own. Heck, most adults don't even know how to properly care for a car, lol.
Welcome.
