The original poster also didn't say the seller DID include the extra. Years of experience with liens and vehicles has shown me how things can go wrong. After I left the salvage yard, I had a badge for 10 years. Perhaps it's a cynicism from years of seeing people get taken, whether accidently or on purpose tends to make one a bit jaded.
If I buy or sell a vehicle with a lien, we all meet at the lending institution and pay cash and satisfy the lien in person. Anything else and things can go awry. Just look at this thread.
