I recently sold a 2010 Prius IV but put the stock wheels and tires back on prior to sale. These RS-M's look great and are in perfect condition. Tires are Michelin Pilot MXM4's 215/45 R17 with 2500 miles. Tire pressure sensors installed on wheels as well. Asking $1250 plus shipping.
I would take these from you in a heart beat. But, a bit out of my price range and you are not local. Good luck with your sale.
I'll post pictures later this week but in the interim if you're just interested in seeing what the wheels look like go to tirerack.com where you'll be able to see the wheels ( they now only stock the 16's) and with their online tool you can see what the wheels look like on your color Prius.
