Hey I didnt bother to read everyone elses opinions or thoughts but did read the original post an thought I would just make these comments.

1. The new owner cannot be blamed for purchasing his car from someone that puts now value on his own word. The new owner likely just bought the car for the reasons we all do.

2. I do not purport to be a lawyer and since I live in Canada it may be different elsewhere but, my understanding of Contract Law is ....

There must be OFFER and ACCEPTANCE and something to BIND the deal. So if a person offers an amount and someone accepts that amount it is still not considered a contract. BUT.... if the purchaser gives a deposit of some value, (example.. hands over $200 cash or cheque as a deposit), Then you have entered into a contract. So... if the purchaser bails he loses the deposit but the seller has been bound to the agreement.

It is always best to get these agreements in writing and have a record of any deposit though. Remember boys and girls....
