Most dealers I have seen are selling at MSRP with no markup. There's been a few I have heard of that are trying to sell for well above MSRP. Nobody should pay more than MSRP. In my opinion, everyone should pay less than MSRP. It's like buying a house. You should never pay more than what a house is worth, and everyone tries to pay less than that. If you find a dealer that is asking for more than the MSRP, go somewhere else. That dealership is not worth getting scammed at. These vehicles are not in high demand. There are simply not enough at the dealerships just yet. Give it a little bit of time and there will be plenty to choose from. No reason to give the dealership an extra $10K or $15K tip. Especially when you can go to another dealership and get one at MSRP or less.
I've heard the invoice price and MSRP are within a few thousand dollars of each other. If that's true, there's really not much room to play. I imagine that's why a lot of dealers are selling for MSRP with no markup.
The Wagoneer and the Grand Wagoneer are both on the affiliate pricing list. If you buy the $100 Individual membership level from Tread Lightly!, you qualify for FCA affiliate pricing which is 1% under invoice. You do have to wait 30 days after purchasing the membership for the affiliate pricing to be available to you. It is said that FCA is very strict with this. You also get a lot of other discounts with your membership.
