Well this forum is way outside the Box of smart USA. This forum has no affiliation with smart USA but is defiantly the most active.
When you post here with a question you usually get a response within the Hr and quite often you will get more responses than you expect. If it has been discussed before you will quite often be given a link to a previous discussion by someone who had been around long enough to know about previous discussions. You then can look over that discussion and you will find folks will also contribute to your new post.
Enjoy the forum, there is lots of information in here as well as at the Homepage for smart car of america
If you want the official smart usa forum for to www.smartusainsider.com But it is no where near as active and informative
