I emailed my Delivery Experience Specialist yesterday and heard the following today:
"I was just informed by our management last night that the delivery windows have been shifted 1 to 2 weeks later, so I would expect that your car to be ready toward the end of October or early November.
I’m sorry to be the bearer of bad news. We know it is frustrating as you anxiously await your car. Please know that we are working around the clock to bring you a car that will blow you away. As we ramp up, it’s very important that every car we produce is quality tested and a product that we will stand behind; just a week or two more allows us to ensure that. "
I had been given a delivery window of October 7-21 for Sig 731 (Sig Red, Perf, Lacewood, Pano roof, Child seats). While it's disappointing to hear about the delay, I appreciated his prompt response and his directness.
