I posted a very bad dealership experience I had to both /r/Kia and /r/askcarsales. The Kia thread had more than a hundred comments, 99% supporting me and my decision to shop elsewhere. The /r/askcarsales commenters immediately started making up scenarios in favor of the dealerships, assuming I was mean, condescending, arrogant; basically all of the characteristics the salesman actually demonstrated, they tried to pin on me.
