Might be right. My wife suggested the same thing after the last persistent guy wanted to purchase the Burb. She said I should have some small stick on signs made for the back window that read "Not For Sale".
The last guy left a note with his number, which I ignored. Then he left another, so I called and told him it wasn't for sale. He told me everything has a price, and I told him my price would be crazy high. He said to "try him" and I said I was afraid he'd say yes, and then I couldn't replace it with anything I liked as much.

 

just got a call from the owner, she said its her sons car and he actually traded it for another car and its being moved in the next few days because the people who took the trade just got a garage.
