They're a bad example of pricing trends. The OEM might kick up some option by $500 but they turn around and run $1k more rebate on everything. Is that a $500 increase or a $500 decrease?

>Almost all cars have differences between sticker price compared to what you can negotiate as the purchase price. In some cases, you'll pay more than MSRP because of limited inventory and popularity. In other cases, you can easily pay less.

Only pickups routinely have manufacturer rebates in the $10k range. These are manufacturer rebates paid by the OEM. You either qualify or you don't, no haggling needed. We're not talking about small differences, we're talking about changes as high as 20% (10k off a 50k truck), sometimes more. Other vehicles do not have that massive error bar tacked on to their price over time graph.
