FWIW, and I don't know if it makes anyone feel better, I called some Hyundai dealers and asked about the Santa Cruz Limited (top-o-the-line) - all dealer are adding market adjustment of at least $2,000, AND adding $2,000 for the dealer added the package, and adding the dealer package even on their used cars - not dealer added factory accessories, but that tint/wax/door trip/etc crap that you can buy for $400. - so minimum $4,000 over MSRP. Now, that's for a car that that is scheduled for arrival in April on a hot model.
Moral of the story, If a dealer wants "only" MSRP on a new Mazda, it's not that terrible.
Or, if shopping for a used car, Carmax may end up selling a used car for $1,000's less than a dealer is selling a used car
