Those doc fees stick in my craw too. Didn't realize that those had gone sky high recently. Dunno about your state, but in mine the title application is done thru the DMV, total ripoff for them to charge that much money just to type up the application...might take them all of 5 minutes to do. Last 2 vehicles I bought were in a neighboring state where they didn't even have my state's forms, tried to charge me anyway. Told them it was a deal killer if they didn't drop those fees. This was pre-covid, and it was still a buyers market so they folded. I would have walked if they didn't.
We can only hope. Dealers are slimy enough in the best of times, the last couple years have brought out the worst. Used car lots are even worse.
Unfortunately, the game is rigged, and if the manufacturers intentionally keep the supply low customers don't have a lot of choice.
