Market adjustment markups: the sticker above the sticker
Walk up to a popular model on some lots and you'll find two stickers in the window. The first is the factory Monroney β MSRP, standard equipment, destination charge, all regulated by federal law. The second is the dealer's own addendum, and somewhere on it sits a line like 'Market Adjustment,' 'Additional Dealer Markup,' or simply 'ADM': an extra $2,000, $5,000, sometimes more, added on top of MSRP for no reason other than that the dealer believes someone will pay it.
Be clear about what that line is. It is not a fee, not a tax, and not a cost the dealer incurred. The factory sticker already includes the dealer's margin, and the dealer also typically collects holdback β roughly 2β3% of MSRP β from the manufacturer after the sale (see 'What is dealer holdback?'). A market adjustment is a price increase the dealer grants itself because demand for that model is outrunning supply on that particular lot, that particular month. It is 100% profit, and it is 100% negotiable β the strongest evidence being that the same car frequently sells at plain MSRP, or below it, at another rooftop the same week.
The markup survives on two tricks. The first is that it's printed. A number on an official-looking addendum sticker feels like policy rather than an opening bid; most buyers who would happily haggle over the vehicle price treat the addendum as weather. The second is bundling: the ADM often shares that sticker with nitrogen tires, VIN etching, and paint protection, so the whole block reads as 'what this car costs here.' (For sorting those lines, see 'Every car dealer fee, ranked: keep, negotiate, or kill.')
The counter is not a clever script β it's changing the number you shop on. A market adjustment can hide inside 'a great deal on your trade' or 'only $30 more a month,' but it cannot hide inside an out-the-door quote. When you ask every dealer for one all-in, in-writing OTD number and compare them side by side, a $4,000 addendum simply makes that store's number $4,000 worse than the store one state over without it. You don't have to argue about the sticker at all; you just buy where the total is honest. (That comparison is exactly what our free OTD calculator at saveoncar.us/otd-calculator is for.)
Geography does a lot of the work here. Adjustments are local β a model that's marked up in one metro is routinely sitting at MSRP in a lower-demand market a few hundred miles away, and transport usually costs a fraction of the markup (see 'Buying a car out of state'). A dealer who knows you're comparing their OTD against out-of-market quotes loses the scarcity story that props the addendum up.
This is one of the clearest cases for how SaveOnCar negotiates: we put dozens of rooftops β including out-of-state ones β into writing against your target out-the-door price, and a 'market adjustment' either comes off the deal or takes that dealer out of the running. The sticker above the sticker only works on a buyer standing alone in the showroom. It doesn't survive competition.
