Act like you really, sincerely appreciate the business. A new automobile is usually the second most expensive purchase a person will make in life (a house being the first). I presume I speak for others when I say that when I make a $30,000+ purchase I would like my expenditure to be appreciated. I don't feel like it was when I purchased my new Ody. I have been thanked much more profusely and genuinely after purchasing a 53 cent coffee refill at the local QuikTrip convenience store. My Honda salesman was more interested in getting us out the door quickly; getting all "excellents" on the dealership survey; and getting us to purchase the overpriced extended warranty. He got none of the three.
