Okay, I think a lot of you guys are failing to realize other factors at play here. A lot of the vehicles missing from the list are known to have a strong following and are always in high demand in the used market. The Accord, RAV4, and Cherokee (assuming older generations) are used car icons. You will get a lot more money selling them your own as opposed to using dealer trade in. People know if they have an in demand used car, and the used car market prices reflect that.
Now, if you have a 2005 Ford Taurus for example, that virtually nobody wants in the secondhand market, you’re best just trading it at the dealership and negotiating as much as possible for it.
Many cars are worth a lot more selling privately than what the dealer will offer on trade in.
