Check out Flood Ford. Same ESP dealers are selling but they are high volume so they are considerably cheaper. Super good reputation in the Mustang and truck communities.
I highly doubt this will be a problem. Service makes all the money and could care less about a couple vehicle sales. The techs will be just as professional making repairs.
Ford could shut this down if they wanted. Really how many FE reservations were made to Bison Motor Company on 7/13/20? They should delete the reservation and refund his $100 for being shady.
