if you're just joining for x-plan...there are plenty of dealers out there that can beat xplan pricing. I beat x plan by $2k in baltimore. $5k off msrp which was $2k off invoice for GT with all options except adaptive cruise. That's why I drove over 17hrs total there and back to get it!
I joined years ago when I started restoring my '66 GT Fastback, but dropped it. Rejoined so I could get the X plan. Wasn't willing to play the negotiating game since I placed my order on May 20th when the order banks opened up. I was driving borrowed cars, and I needed a new car ASAP.
