I'm looking at this used bike:
...for only $40.
Now either this could be a very good deal or it could be stolen. The bike is fairly new, so why would it be so cheap?
Anyways, what are some good questions to ask the seller to verify that they are the original owner? I may not be able to ask some questions because it (supposedly) belonged to his sister and it's a good alibi if he's unfamiliar.
Any good questions to ask?
