I ordered some grill extension pieces, which arrived with duplicate upper pieces, instead of left and right. I contacted American Muscle and thus began the saga of never ending excuses and so many emails to simply get my correct parts I had already been charged for. Went on for months. We contacted an individual from parent company (Turn 5) to try and get resolution. More promises... we will get you taken care if etc. I eventually filed a complaint with the better business bureau. American Muscle told the BBB that "the customer hasn't been charged" which I pointed out to the BBB as a complete fabrication with a screen shot of AM's lie. AM then said, we meant the customer hasn't been charged for the recorder... what the what. I can deal with slow and inefficient, particularly for something specific like a MMD part in this case. I eventually got a refund and shipped back the wrong parts. It would not surprise me in the least if that same box of wrong parts gets shipped to another customer. It is as though young children are handling this companies affairs. Plenty of other Mustang aftermarket suppliers out there sans the major disfunctionality. I bought a new exhaust from LMR recently and other items from CJ Pony Parts. I scraped off my American Muscle window banner and asked them nicely to delete my acount which of course they haven't done. Eventually this stuff will catch up with them in all likeliehood from a business perspective. I had spent well over a thousand dollars over a few years with them.
