Going to buy one off craigslist. Guy wanted to show it to me in a parking lot. I said if I can’t test it, I can’t buy it.

Agreed to meet at his place so he can plug it in and show me it works.

Other than it working right then and there, should I be on a lookout for any other kind of issues? Overheating? Oil leaking? Radiator hoses? Bad Am/FM reception? (yes, I know it doesn’t come with radiator or stereo or oil - JOKE)
