If a dealer can't keep his toilets clean, how well do you think he manages the rest of his business. The most important thing to remember about buying a new car is that the typical salesman or saleswoman is not your friend. Oh, some of the really good ones may actually be your friend and act as much on your behalf as on the dealer's behalf. And the very worst ones may actually have no regard for you or your needs. Regardless of the dealership he or she works in, remember that the salesperson is out to earn a living, and the quality of that living depends on the deals he or she strikes.
Smart dealers know their long-term success depends on a good reputation.
But the turnover in salespeople is notoriously high. It's a tough job with long hours and, for many, low pay. And because he earns his livelihood selling cars, a car salesman knows far more about selling than you do about buying. Despite a friendly attitude, he is not really your friend. Try to find a salesman or saleswoman with whom you feel comfortable.
