I’m a big advocate for social networking between customers and businesses. However, I think this used car dealer might want to try a bit more tactful approach! At least he does present some very good facts about how he runs his business, and is engaging with the customer. Perhaps CARFAX needs to offer a “Used Car Negotiator” along the lines of Priceline’s Negotiator!
