FYI - promotion in effect is taking at least 1K if not 2K off the price. At least that's based on what I've heard from dealers ranging from NY down through SC.
I purchased my GC1720 on 7/18/15. The dealer quoted me one price and when I went in to sign the documents, the price was $2500.00 lower. I got the GC1720 and the MMM for $17,000.00
