Well... here I am ready to make the deal for a 2015 Stang ecoboost and agreed to price. All is well. Now the Mk3 trade they offered me $8,000 I politely asked to speak to the Sales Manager at Gus Machado and they would not budge. I POLITELY told them to shove it. $10,500 is fair I left. Chevy offered me 11,500.
