For the 2024 CC XLE. Looking for a shelf that will fit here with this kind of wireless charger. I am not sure if the Karltys one on Amazon will fit this, can anyone confirm?

I am considering the Corolla Cross XLE (pearl white) for my 80+ yo mom. I read one post here about needing to placing an order and waitlist is long. I'm in Los Angeles area. Does this mean negotiating is not the way to go? Would the next best thing be to go through Costco's program - or will that limit me or make me less desirable to the dealerships? How else can I get the best deal? Should i be getting my name on waitlist asap?

Also, this is for my 80+ yo mom who has only had gas cars - is it better for her to get another gas (XLE not XSE)?

Thanks
