I would check size of section that fits cupholder. Ghibli cup holder is small.What did you end up going with? I'm tempted to get this: Amazon.com: Mediabridge Smartphone Cradle with Cup Holder Mount - Car Cup Holder Mount for iPhone 6/6 Plus/5S/5C/5/4S, Samsung Galaxy S5/S4/S3/Note II/Note 3/ Note 4, HTC One, Motorola Razr Maxx HD (Fits Smartphone Widths of 2"-4"): Cell Phones & Acc
Cupholder makes some sense since the power plug is right next to the cupholders - and it can easily be stowed away in the center console when not in use. Vent mounts don't make a lot of sense with the way the Ghibli vents are tilted. I typically only want a mount for longer trips where I need Waze to give me warnings. On short trips, my phone typically just rides on my lap.
*caveat: I don't own a Ghibli, yet. Still awaiting delivery on my '16 order.
