What do customers want/expect from dealership web sites?

Like every other aspect of Auto Retailing, the dealership's web site should provide the information and services that customers want. However, the Internet is a relatively new medium, and it may not be clear what customers expect from a dealership web site.
Even if you think you know what customers want, integrating on-line services with a dealership's established practices can be a big challenge.
Other dealers are interested in your experiences with these issues, and we are sure that you would like to hear what your peers have to say. Here are some questions to get things started:
-What are customers expecting when they come to your site?
-Are you able to provide the information and services that customers are are looking for?
-What are some of the biggest challenges?
