There is a time and place for objectivity. Yeah, the guy is a jerk but I like the vehicle and the price is good.My opinion is you are wrong. Classic "cut off your nose to spite your face". "Rewarding tactics"? Beyond having empathy that the guy has to eek out a living, who cares about anything else except that you end up with the car you want at the price you want? This is a business transaction, not a Kumbaya, hand holding event.
Reminds me of my tactic as a 5 year old to punish my mom. If I was mad at my mom, on a cold winter night I would go to bed without the covers on to punish HER. "I'll show her", LOL. I also remember her rocking me to sleep at 2 a.m. in the living room on a cold winter night that I was very sick. She died this past December 26 after a full life of 91 years. Still processing the memories and everything (apologies, but it feels good to share).
Sorry about your mother.
