Im buying a used Etrac how/what should i test

[Backstrap80]

Hello, I found a 2 year old Etrac for sale, The problem is, I've never held one. I know the Xterras, and a few others but I have no idea what to check for? Or what set up to test in. I will watch a bunch of videos if anyone can explain anything or link a helpful vid, I'd appreciate it.
