You know how to check for chain wear with a steel tape or scale don't you. If it's more than a 1/16" out, probably that needs replacing. Know the cost of a 10 speed chain. If the chain is more than 1/8" out, then the ring or rings might be worn too as well as the cassette.

Add these little things up in your head as you look at it in person and decide if that is worth it to you and ask for a reduction in the sale price.

You are going to replace those tires too aren't you? 35 bucks each for decent tires.

And also realize that 10 speed chains and parts are getting scarce too in some areas as is 11 speed stuff. So if this has too much that need fixing now. You might not be riding anytime soon.
