Bob, welcome to the forum and your 'new' i-MiEV. You're now the proud owner of the most under-appreciated new-generation EV in the US - you'll undoubtedly end up using it for most of your daily trips and find yourself questioning the sanity of the 'professional' reviewers who slammed it.
Try not to discharge it below about two bars and don't bother fully charging it unless you're about to set off on a longer trip (it's better for the battery not to leave it fully fully charged, especially on a hot day).
Most of all, have fun and use it!
PS. Some of us take off the headrests for better visibility unless they're needed by passengers.
