Just a quick quip on this topic.
I think the biggest mistake dealers make today on their website's is taking the old-school, sell sell sell approach. While some websites are enhanced and flashy, most still use a generic "we're online 'cause we haveta" approach.
An earlier posting mentioned that most customers will click on your website while just browsing, not in "purchace mode". This being the case, give the client something to do and look at while he/she is just browseing, and hopefully retaining the customer when it is time to buy.
How to do this? Make the site interesting, and a source of new, up to date information. Post something on the page that a normal client would not have access to. Dealers recieve a ton of interesting information everyday, why not share it. Make the site informative... include a open recall search page in the site, ask the customer to ask questions. One of the biggest keys is communication...ask for email...respond promptly...do legwork work for surfers - because tomorrow they may be looking to buy, and you may already have a relationship.
Looking forward to responces, Dan
