When I see the preponderous positive reports on our dealers it reminds me of the ( FORMER) new car dealer adage. Sales provides the first new car, Service sells every car after that.
If I'm reading this correctly, that goes for almost all vendors. They do something to get you in the door, but continuing levels of service invite repeat commerce. If they decide to cut corners, their cliental fall of accordingly.
