The RAV4 Prime is extremely hard to get if you live outside of SoCal and maybe a few other areas. I'm in the southeast and a few years ago the local dealer told me that this entire region is only allocated a few Prime's each quarter. Even today I've never seen one in the wild.
Not only that, but it sounds like dealerships are still hardcore ripping off people who want to buy a RAV4 Prime. $20k over MSRP, refusing to sell without add-ons / warranty, etc.
