Reliability. My friend's CTS has headlight connectors that have melted and this after them being replaced on a recall. He bought a wire crimping kit and put individual connecters on each wire to have the headlights function properly. After a bad winter storm 2 years ago his ABS and traction control system said "enough" and has been without since which recently cost him 2 new front tires after a major lock up. His father in law bought a 2014 ATS and took it in for an oil change recently, they thought they would take care of a recall item as well. When he went to get the car the entire dash was on the front seats and he picked up his car EIGHT days later, safe to say that reliability is is indeed a factor when purchasing a Cadillac.
