The best way is to be up front. Kno w what you want to spend. And don't break your own budget. That way it's easy to make comparisons. Any old dealer can sell on price, but it takes a real one to look after me.
Service here means being taken care of both during and after the sale.
It's too bad that consumers feel this way, but it's a reality. The auto market is price sensitive. A good dealer has become extremely hard to find because of the pressure from the factory as well as the bank to move vehicles as quickly as possible. Overall, it's better to find a dealer who will take care of you. But that may be wishful thinking.
