What would you think if this happened to you?
Seller has a car advertised in a car forum.
Buyer enquires about the car and after a period of negotiation a price is agreed. Buyer arranges to view the car at the earliest convenience and to put a deposit down subject to viewing and test drive. Seller and buyer discuss method of payment of balance.
In the meantime the buyer arranges finance for the car etc. confident in the seller and description of the car.
The day before viewing the seller informs the buyer that there is suddenly another interested party who is willing to pay more for the car. Essentially the buyer is told he still has first refusal on the car but must now match the offer made by the other interested party, which is £700 more than the price agreed.
How would you feel if you were in the original buyer's position?
Seller is not on this forum by the way.
