Yeah, maybe it doesn't make sense for everyone compared to the Model Y, but it will for many. I was going to get the standard hybrid XLE plus weather package before I heard about the Prime. The Prime SE will be cheaper for me than that due to the tax incentives. I'm comparing a base Prime SE at $27,720 ($39,220MSRP minus $7500 federal + $4000 CO state) with a Model Y AWD LR at $48,990 ($52,990 minus $4000 CO state incentive only). I get it - if you're planning to load the Prime up, the prices become a lot more comparable, but that's a lot of stuff I don't really need, leaving a $21,270 difference...
Toyota still has plenty of federal tax credits remaining, and currently only the Prius Prime qualifies, so they're probably not going very fast right now.
I love the Model Y, but it doesn't make sense for everyone that is considering the RAV4 even at the same price. I spend a lot of time exploring the desert southwest camping, trail running, hiking, doing photography, and I've tried to think of ways to make even the longest range BEVs work for that, but you can't yet (We already have a 200+ mile range EV in the household, so I know exactly what that entails). The fast charge infrastructure doesn't extend far from major highways and large cities.
The one aspect i left out was if someone was using their vehicle for trails (because i think most don't) and just want the higher vehicle and something for the snow. Even though a BEV (especially Tesla) is better than those due to the extreme low center of gravity and advanced traction control.
But ya, your situation makes sense. Especially with already having a BEV. New toy, lol.
ALSO - I see Toyota marking these vehicles up some on the lot. This is just the MSRP, so god only knows what these places will charge knowing that there is a high demand.
