I traded in a car here when I was younger - they saw me coming from a mile away - the sales person sold me the car with dealer financing at 15% (did not have much credit). A few days later asked me to come back after they had my trade in and said that due to a paperwork problem they would need me to sign again, this time at 19%. I felt pressured to do so and didn't have anyone to turn to for help. I trusted they weren't trying to take advantage of me.. LOL.
They taught me a great lesson. These days I don't bother with dealerships, nor financing, and have a lawyer on retainer for any large purchases. Do yourself a favor and buy a car outright off craigslist or buy a Tesla instead. I hope in the next 20 years this whole dealership (aka, "stealership") model collapses and these places go away completely.
