I love it! This is what the internet is about... transparency for all. Now you get to see how your competition is faring, as well, at least on AutoTrader.com and Cars.com. The shopper rules online, and they trust reviews from their peers far more than they trust a sales person. Managing brand/ dealer reputation should be a daily activity, and monitoring scattered social media conversations can be daunting, but one bad review sitting out there for three months before you discover it will prove how essential it really is to do. There are some very powerful tools out there to do it for you and help you review and respond (SocialDealer, GOSO, etc.)--even an aggregation tool like Google Alerts is better than nothing; but clearly, the time is upon us all to increase awareness of what shoppers are saying about us (and our competition)... and get in on the conversation.
Disclaimer: I work for HomeNet, and we are partners with SocialDealer... but that doesn't change the truth of my words.
