The problem is there are too many brands. Get mad at the GM deal, 3 years latter buy a Ford, then decide it is American cans and replace the Ford with a Honda, Honda is bad buy a Toyota, then onto Volkswagen, Kia... and back to GM because maybe they have gotten better in the last 20 years.
Dealer loyalty is not something you have so they have no incentive to make you want to come back: you probably won't anyway. If you a a buyer for a large company (ie a fleet of plumbers) you will find your dealer is more responsive. Not only does it get the large sale today, but he knows you will be back next year for more if he treats you well because there are advantages to having all one make of vehicle in a fleet.
