Your supposition is that I said we need laws for this. I claimed dealers add value. You're arguing the wrong point with me.

That aside, your notion of competition implies all dealers have like models, which is incorrect. Sure, they all have sedans, but I've yet to find a Honda I feel comfortable driving in. There's plenty of other factors, too. Locations, maintenance schedules, manufacturing origin. It's not all that dissimilar from there being different laptop manufacturers.

So, if I really want a Ford (which was the example here), it's nice to have competition between Ford dealers. Otherwise, Ford could just become complacent. Likewise, I'd hate to see fiefdoms form where you really only can realistically buy one or two manufacturers because the third one determines moving in wouldn't be profitable enough.
