If anybody has any experience with Jaguar, they would most likely to agree your lucky if the engine starts. Jaguar compared to a Cadillac CTS? Umm, nothing to compare at this crossroad. I beat up some GM cars on certain aspects, but the CTS is clearly a world beater in it's class. Even the previous CTS was a good deal for performance and styling. I'm not sure of the reliability of this new Jag, but these cars have proven to be unworthy subjects in a modern world of competing cars that will actually start in below freezing temperatures. I won't even start to talk about the lousy Ford drivetrains they are based on.
