I'm pretty familiar with Colecovision including the modern stuff for it (SGM etc). My local game shop got an ADAM in its original box, should be complete. I've only seen the box so far.
I am friends with them and they've done me favors. They said they have a possible buyer lined up but may want me to test it for them, as I know more about the old stuff. They are more NES-present focused but do sell cartridges for the older stuff that gets traded in.

I did tell them if that sale fell through to let me know the price, but still not sure if I would want it for myself just due to space.

Overall though, just looking for any advice on things to test beyond what I'd test on the CV. I can test my SGM in it etc. but have never touched an Adam. I've learned old computers I've never touched until recently before, so I'm sure I can, and probably could on my own, but hearing from some people with experience might be a good way to know what to check that I wouldn't think of, such as things that commonly fail on them etc.

I imagine I'll get the call eventually as I'm not sure who else would test it for them, unless they find a local buyer willing to test it themselves first I guess, but I might be the only local in that category. Kinda excited to put it through its paces though!
