Good point here. I qualified for $3250 in total rebates from Ford when I financed with Ford Motor Credit on my 2013 GT.
FWIW, I got my base GB 2013 GT 6M with the tech and SYNC packages for just under 28,000. It had 4 miles on it! I don't think I have ever seen an odometer with 4 miles on it! it was kinda weird. LOL
On the lot that I purchased mine from, they still had 1 2012 V6 with the MCA package (no 2012 GTs) that they would let go for a song. It's a buyers market right now.
My car had 2.8 miles on it when i bought it.
