i bought one of these last time expecting it to be a little dinged up, but it looked like mine had been dragged across a driveway. Probably these were used in a school for a year and you can imagine the condition of one of those. Just so you know…

Seriously, my Lenovo refurb was OK, but the keyboard was very worn and failed. However I have never seen another more repairable unit, even with online instructions from Lenovo!

Fewer scratches and dents.
Before buying an older Chromebook, look at when it reaches end of life for ChromeOS updates:
