I work for a rental car company and we have more service issues with Caddys than any other car. GMs sticking too much crap on them, and the more complex they get, the more that can screw up. I personally had one break down on me in BFE (in between Sioux Falls,SD and Sioux City, IA), after that, I vowed to never rent another one. It was 30 below zero, and I had my 6 month old son and wife in the car, not good I will tell you.
