That's why I've followed all the google university advice to just stick with an internet sales guy and keep it to emails until you have your negotiated price in writing. Walking in the door before that is asking for frustration, aside from bouncing around doing some test drives, but if you know what you want then just search and email. They bother the fuck out of you after you've made contact but its easy to ignore. You can hang up the phone without answering or whatever and they'll still be super polite and shit of course.
That other place never emailed me back. I don't know if someone knew my name from having left it with them at the test drive, but they probably saw my message asking for out the door and what any unexpected fees would be and said forget it. I read yelp reviews of the place confirming that other people went in chasing their low online price, only to find thousands tacked on in "reconditioning" (on a two year old car with one owner and 40K miles?) freight (seriously? from where? on a trade in?) and one guy said they charged his sister $1600 for state inspection. This place is putting inspection certs on shit all day, doesn't their own service department handle that? Even if not, I know from buying and selling multiple older cars on CL that the inspection stations near me charge like $75-$80.
They are just getting people in the door with the way below market shit then hoping they will be stupid or pushovers or just give up and want the car when they run their scam "there's nothing I can do about this fee!". Really, its not like the price is way over market or book, just that it rubs people the wrong way to trick them onto the lot with those advertised prices. Better IMO to stick with a stealership that's willing to give you an actual up front list price online with no hidden fees and then quibble over the final price.
