I bought a NEW 2018 Mustang GT and it broke down after 20 miles. They've been trying to fix it for TWO weeks since I bought it and they have NO IDEA what's wrong with it. The worst part is the customer service. It's sub-par. I don't think Woody Anderson or Ford Motor Company cares that I just bought a car from them. I'm finding out afterwards that friends and colleagues have had similar experiences with their lackadaisical service. I've always been a big Ford fan but now I'm starting to think I should have bought a Camaro SS.
