Honestly, I recommend studying up SEO and other web trends so that you can make an educated decision when selecting a website vendor. Be warned that many of the bigger vendors use copycat website content on your pages and out of date SEO techniques, so it may hurt your rankings.
After being tired of vendors not providing us with the options that we want and charging us an arm and a leg for sub-par products, I have actually decided to ditch going the traditional route to actually self-host and build our new group website from scratch on the Wordpress platform with help from the
DealerTrend Inventory API to facilitate the inventory portion of our new site. I'm nowhere near finished, but you can check out my progress here:
Thornton Automotive . The site is fully responsive, and I am able to completely customize EVERY aspect while keeping up with the coolest website trends... Plus I can totally own our SEO tactics.
I work for a small automotive group that has a Chevrolet dealership and 2 (soon to be 3) used dealerships. We were looking for an option to make a group site that features inventory from all of the rooftops while we are going through our group re-branding process. After tons of research and demos with various vendors, I am SO happy that we have decided to go this route. Not to mention, we will be paying only a little bit more for our group site than we were paying for only 1 of our used dealership's basic Dealer.com websites.
I'm not a web designer/developer by trade (I went to school for Public Relations,) but as long as you are willing to put the time into learning, building your own site is possible (and very rewarding!)
