I thought the performance pack was the LSD, launch control and shift lights? So if it has them it has the PP, that said, currently on the Ford site the PP is standard on the ST3.
That is what I understand. Launch control only comes with the performance pack, and the performance pack is now standard not an option.
I aren't sure when the car I drove was built. It was unregistered and had to be borrowed out of another dealers showroom. It still had shipping stickers, and plastic covers on it. So it could be a new build or built a year ago.
Emailed the salesman to confirm it has it. At least then I will have proof that he told me it had it.
