I also checked out your site, and I think it looks great. I'm looking to upgrade so have been doing it on line. Which saves a lot of running around to the various RV lots. I'm not interested in a new MH, but would like to have a place to list my want's and if you find what I'm looking for then your company could act as broker for a commission to get the seller and me together.
If their idea is to go more global or nationwide, they must consider all aspects of their business. The only way they are going to compete with the local dealers is provide something they can't, which being as much as a couple thousand miles away from some prospective customers would be difficult.
However, there are others out there doing such a job, and where they beat the locals is in the prices. Obviously if you're going to "lure" potential customers to your website and that dealership from afar, you're going to have to make it very much worth their while. I'd drive a thousand miles to save a thousand dollars, but wouldn't do so for any less!
Check out this place in Wisconsin, they sell nationwide and claim to do it at Factory prices (not exactly, he has to have some kind of mark-up or he would be out of business). I have "talked" with several other people on the Popup Times message board (same Snitz forum as this) that have driven from as far away as Maine and NJ to purchase units from him, solely based on price and the amount of money they were saving.
WOW. 33 pages of "NEW" inventory, and no way to search by model, or type. I know that if I am looking for a popup I don't want to have to look through pages & pages of Motorhomes, and viceversa. I would suggest that you include a screen to enter search criteria, and make the entry of each field "optional". ie: if you arent presented with an entry, don't use it. Also, if you are going to include a field with "PRICE" don't put "CALL DEALER", otherwise why have it. You have a very good start, but you have need to differentiate yourself from the others if you want to make this fly. Good Luck
