The GM link to the dealership website

Why does GM put it’s dealers in the situation to choose between settling for a blasé website in order to get the coveted link from GM sites?

At time when GM really needs to get it’s sales going it seems that they would want their dealers to have appealing sites that actually get customers to submit requests on a dealer’s inventory.

Fortunately I think more customers are actually hitting dealership sites before buying than the manufacturers sites, so the “link” from GM is less important that it used to be.

I’d like to hear from GM dealers to see what you guys think about the link from your GM site.
