Dealer tracker. Last year I went to buy a used 2022 RAM 2500. Got to a good price and started going over the invoice line by line. I noticed $1400 for a "stolen recovery module". I asked about it and dealer said it tracks stolen vehicles (requires a monthly fee), ie. LoJac. I politely asked them to remove the tracker and dealer said they install them in all their new and used vehicles. I then asked not-so-politely to remove the module and remove the $1400 charge or the sale is no-go. They wouldn't do it so I walked out. Won't visit that dealer again. That really lit me up. And when I purchased my new 2500 (at a different dealership) my first question for salesman was do they install trackers, he answered, no, never.
