Regarding pricing increases.... Once you order your vehicles and get a priced order confirmation, the dealer is able to claim price protection when your vehicle is delivered and they nvdr it (register you as the delivered owner with Stellantis). However, they have to do this step correctly.
If I was not your selling dealer, ask them if they will be using the price protection lock at delivery to guarantee the price you were quoted isn't increased. They should not act like a deer in the headlights. Lol. Ask in an email, and hopefully get the response by email so you have it in writing in case they try to increase the price on you.
If you are sitting on the fence about ordering, you may want to jump in now to lock your price, as I I would imagine prices will continue to rise because of the chip, metals and transportation shortages. Manufacturers will have to pay more to guarantee supply. And that will be passed on to you. Again, I can't see into the future. It's just plain logic of supply and demand.
