You made a wise choice to check it out here. Yes, there have been some problems, but that is centred mainly on earlier production versions. The Sync is the Achilles heel right now, but Ford is working hard on solving the issues. There are updates that members are just starting to have done recently that will help solve most of the problems. I was contemplating a Hyundai Genesis and saw so many members having so many problems that I crossed the car off my list. I ended up ordering an MKX and couldn't be happier.
I75 is a workout at any time!! I'm usually taking it or I-94 when we cross into Detroit. Where abouts are you? The features this car has is just sick!
The wait always seems longer when you are anxious to get it. There seems to be a shortage of the 3.7 engines too as they are used in Mustang as well as F150. It will be worth the wait. You'll probably find a little less modding here than the Mach 1 forum though, eh??
