The only crazy mark ups I've seen down here from personal experience is Raptors.
"Regular" vehicles I know from talking to salesmen that I know and trust tell me they add 3-3.5k on top of trade in at most depending on the price of the car. Leaves them some wiggle room, but of course down here almost every dealer had a $500-800 dollar dealer fee.
With a trade in it could become more complicated in that they may drop the price of their car but "lowball" you on trade. Get a good idea from Carmax and other instant buy dealers to see what type of trade in to expect or shoot for. I've noticed recently I've gotten better trade in numbers from regular dealers than carmax, and the selling price seemed fair to me.
