Abstract: An online system that allows a buyer to find a car for sale and interact with a car dealer whilst remaining anonymous for as long as the buyer chooses. The buyer submits a request for a car quotation that is forwarded to matching car dealers. If a dealer provides a car quotation they incur a small charge. The quotation is forwarded to the buyer and an online chat channel is established between dealer and buyer. The buyer may chat with the dealer while remaining anonymous. If a quotation is not acceptable they buyer can end the chat and hear no more from the dealer. If a promising quotation is received the buyer may divulge their contact details and make further arrangements with the dealer such as a test drive or trade-in evaluation. Once the buyer has decided on a car the quotation request is completed.
