If you want a really honest dealership, you could search for Big Bill Cars on YouTube. Bill's last name, a four letter synonym for perdition, is censored, and the video uses foul language so if you watch that video, please do so when nobody is home, turn on a fan, run the sink, flush the toilet, turn on the shower and put your headphones on too - so that the surveillance bug in the wall wouldn't hear the language in the ad, either. If you have an air compressor, table top saw or cheap angle grinder, now's the time to turn them on too. Unplug your smart TV from power and toss the remote somewhere very far away. Some remotes have microphones built in now. Then carefully toss a blanket over the screen so that the ad's visual elements, which also contain written profanity, do not catch the eye of any video surveillance devices either. This is, of course, after you've shrunk the window down to 1/4 size so that only you can see it by squinting up close. Oh, and leave your phone in the mailbox too, with the battery removed.
(I mentioned this ad once before, years ago, in very hushed and veiled terms. Even then, I still got warned by management that if I had indeed linked to the ad in question, I would have been erased from existence as far as the site is concerned)
