Buyer: Can you tell me about this cart if you still have it?
Seller: I don't know much about it, it was left to me. I was hoping a niche buyer would want it. 
Buyer: I just need to know if it rolls okay.
Seller: It does. I added some wd40 and it rolls very smoothly across carpet and my wood floors!
Buyer: Great. I have Tektronix 7000 series scopes and I see it should work with them but it might not.  How about $40.00 for it? 
Seller: Considering I know nothing about it, that seems fair to me. It's a deal.
