For all their grumbling, those places won't want to pass up the market. If even half the hype is true, this car is going to be a winner, and I can envision a healthy aftermarket.....market. If anything, the relatively limited color palette and styling options (which are my only real gripe with the MME at this point) will leave room for 3rd parties to provide various customization choices.And probably any other color. I changed my Mustang Ecoboost Puddle lights to Orange to go with its color scheme of Grabber Blue with Orange graphics.
It will be interesting to see if the Mustang vendors like American Muscle will pick up Mach-e mods.
