I must admit, I never get tired of this topic. Internet experts who read an article written by a failed car salesman are totally convinced they can walk into a dealership and leave them quaking in their shoes. Guys whose lifetime experience of buying vehicles equals the dealers last week of sales, just know they are going to win the game.
They are trying to buy one of what the dealer has figured out how to own dozens of and has a multi-million dollar facility to keep them in. From experience, I can assure you these guys are thinking while your sleeping of new ways to sell you. Any ideas you read here, they have already seen twice...yesterday!
