I do everything to be "personel" with my customers. Treat them like a friend. Do extra stuff for them like Scott said. I always say to tell them, "Oh, I went ahead and shampo the carpets". They will brag about getting something to there friends for free. People love free.
Also, If they have a car show, go to it! To show you have there support to win.
Never speak negative. Customers hate complainers, negative people.
