extension

Hi all! I saw a thread a few weeks ago about a chrome source code or extension that automatically alerts you when a new car pops up in inventory! I could not find where this actual extension was posted and was wondering where it was and how to add it. I have heard there are still some SR Model...

40 amp extension for charging? Have a 40 amp extension cord that I want to use for charging my model S. I’m told it should be 50 amp? Does it make a difference. May be a silly question but I would appreciate any suggestions. Thanks.
