Kaihila, if there were no V6 Stangs, there wouldn't be a Stang - period! Historically, it has been the massive sales of the V6 Mustang that has kept the Mustang brand alive - and relatively inexpensive.
You most certainly have a "Stang" - and a very respectable one at that. Don't let this Bozo mess with your head on this!
Look, some people are into their Stangs for performance, some for looks, some for both (me!)...just because you don't have 300HP doesn't mean your V6 Stang isn't as authentic as the GT...
