Sounds like a great deal. Most dealers in NJ aren't discounting them because they sell QUICK. I got mine on D-plan (Ford Employee).
Keep one thing in mind regarding price. It's very common for a dealer to give the car away up front and then hammer you in Finance. Watch your rate, dealer fees, etc...the dealer can make up an additional $4,500 in BS fees, add-ons, and rate bumps. This is becoming more and more common in the industry.
I would recommend getting the Ford Tire and Rim warranty. Those rims/tires are expensive on the Sport.
