Did you speak to Eddie Sosa at Weston Nissan? Also while I live right down the street from Coral Springs Nissan I never went there because their selection of Z's were crap.
Another good Nissan dealer is Endicott Nissan on US1 down near Ft Lauderdale. I forgot the kids' name(he was like 24 or something) but he actually let me test drive a 40th which was amazing I thought.
