Well, if you walk into a Pontiac dealership, and a sales guy tells you how great Pontiacs are, that the quality gap with the Japanese cars is a thing of the past, and that Pontiacs sold today will have great resale value, etc., would you believe him?
More importantly, is the sales guy lying? Or is he just doing his job (which is to sell cars)? I think David L. is doing what he is paid to do. Intelligent consumers should know a sales pitch when they hear one, so IMO there is no issue of being truthful or not.
