So a little update: The title in fact did not come, leading me further to the belief that this guy is lying to me and hoping the title shows up one of these days. I called him tonight, and he told me he wanted to charge me for the miles I put on it. I said that doesn't seem fair since I put less than 100 on a car with 132k miles, and asked him what I should charge for the $5k loan I gave him? And should I kiss the $25 dollars I paid for emissions (state law requires seller to pay that) and the $70 I paid him to replace a wheel bearing goodbye?
Any advice for what seems like might be a slightly antagonistic negotiation here? I think even he is giving up on waiting for the title, so I imagine he will just push back on the amount he refunds as much as he feels possible. If I felt he were being honest with me this whole time, I wouldn't be nearly so intent on getting every dollar back, but at this point it's really the principle of the matter
