From ArchVision’s announcement:
New Cars Now Available in Stash!
We have new cars in Stash! Now you can download, drag & drop, and render Toyota Rav 4, Ford Expedition, Hyundai Elantra, GMC Sierra and Jeep Wrangler RPC Cars directly from Dashboard into Revit! If you’ve used your RPC Creator tool, you can share with fellow RPC Subscribers through Stash! too.
To download the new cars (145MB) click here and unzip into your c:RPC directory (or preferred RPC storage location).
