but i had exactly opposite issue... 
i got a buyer for my car, inspected by 3 persons in 3 different occasions and locations.
Car was also inspected by a reputed auto company. We had dealt for a certain price and ready to process registration. After all procedures, he came down with the price issue which is not at all agreed earlier.
Thanks that the car was yet to transfer.
QL members / sellers, please becareful from such substances which may lead you in confusion and make sure to get the money in hand prior processing paper.

regards,
