As someone who has bought and sold a few cars over the years I can offer a definite and informed opinion on this. Car dealers – particularly their sales staff bring nothing to the purchase process whatsoever. My understanding is that the research also backs this up – the majority of purchase decisions are made before someone enters the showroom.
Yet another example of a group that doesn’t get that technology has enabled them to be completely by-passed and somewhat in line with the thinking of those that run TV stations and department stores.
