Repeats and referrals are the holy grail of selling. They show up with a strong intention to buy a car from YOU. So we cannot do anything that will sacrifice this! If we lie, change dealerships, lose credibility or connection with our customers, they drift off, go elsewhere, and may also tell all their friends and family to as well. One of the simplest value added services you can give some of your customers, create small accumulating gifts of obligation, keep in contact with them (without having to call them) and make sure no small issues become large problems is to tell your customers to book all of their service appointments through you! “The real sales begin after the first sale!” Joe Girard.
