I have given my local dealer a deposit to place me on the list for the GH when it starts coming in. There is one name ahead of mine. When the dealer is notified of what is in the pipeline to them they will contact me and give me the choice of what is coming in and put my name on one. I am hoping one of the early offerings will be a light colored std hybrid in Limited trim. Either second seat configuration works for me. They tell me they will be selling them for sticker with no bump.
So I would say speak to your local dealer and see if a deposit will secure a place on the list. For the regular Highlander local dealers have 30 to 80 people waiting for one to come in. I think once the news of the GH gets out there will be a long list of people waiting to buy on
