School me on Sky Redlines or LNF engines in general

Know someone looking at a sky redline and I am taking a look at it with them on Saturday.
Any ticks, noises or common issues I should be looking/listening for?
From what I have read the LNF is a good engine, but figured I would check in here.

oil filter is a dick head to reach, thats all i know

They’re gonna be noisy with DI. Other than that I haven’t heard much for issues with the LNF. Check out cobaltss.net or a sky redline forum for more info. Or contact ZZP as they make a bunch of aftermarket stuff for that motor

Convertible tops on those have MAJOR issues. I’d say 3/4 of those and Solstices that we get @ my shop have broken tops. $$$

Thanks for the comments, I did read the tops are a pain.
Anything else? Taking a look / maybe buying it tomorrow.
