In my market area, we have 1 large GM dealer (~35% market share), 1 sizable Ford dealer (~25% market share) and 2 small Dodge and a half dozen other dealers. The large Gm dealer is probably the best one to deal with. It doesn't matter who/what you are, or what your budget, they will bend over backward to get you into a vehicle. The ford dealer is almost the same. In fact, I really can't think of a negative thing to say about either one. One of the Dodge dealers is...well....it there wasn't the second one, I would not be driving a Dodge.
I seems the GM and Ford dealers have figured it out. Every person that walks through that door is a potential customer, and if you treat them right, they become 1 less customer for your competitor. I really like my Ram trucks. I am so glad that one of our Dodge dealers is good to deal with.
