Hey @TreyGuy (or others from Markup.org) How do you account for dealers which sell for $0 above MSRP but then include a non-negotiable $700 "paint protection" service? As a crowdsourced site, you'll get a ton of reports that a particular dealership has no markup and few if any reports from people who have actually been far enough into the purchase process to discover these hidden markups.
Right now we are currently accounting for both markup and mandatory add-ons as a total in the same numerical value. If it's 0 markup but $2995 for N2 filled tires then the total markup is $2995.
We are finding the opposite to be true. Most of our posters are folks that have actually spent at least a little time dealing with a dealership and are reporting the numbers back to us. Our hope is that as we get more postings the false or innacurate postings will be drowned out by the accurate quality ones.
