I totally understand what Ford was trying to do by calling it a Mustang. However it really hit hard with the Mustang ownership, probably as big of a controversy as when Ford was going to make the Probe the Mustang. If they have called it the Galax-E, there wouldn't have been as much resentment from people.
FoMoCo has been milking the Mustang marque for over 50 years now.
Just ask all those people who bought Mustang IIs, which was in many ways a Pinto with a vinyl roof and racing stripes.
We've got one of these battery powered, four door 'Mustangs' down the street from us. It never leaves the garage, probably because all the solar panels on the house have been covered with snow all winter.
