My first American car, after several Japenese sedans. The styling and build quality are excellent. I've had a few quirky problems, but no less reliable than the Toyotas, Infiniti, and Nissans that I've owned. The CTS has been much more reliable than the G35 which I traded. The CTS has been a low maint vehicle as I do oil changes and tire rotation only every 10K miles. I've been averaging 20 mpg in mixed driving, which is a bit disappointing, but it only requires non-premium fuel. This is no BMW, but I also paid $7K less than a comparably equipped 3- series and the CTS is much roomier for a 6ft. 200lb driver.
price, AWD is good in the snow, comfortable seats, sporty handling for a sedan, decent acceleration for a V6 but I wish I'd bought the DI-engine for added power, ease of dash controls.
had a speaker problem that took months to fix; could use a slightly quieter ride especially from rear window/door area, better gas mileage (or offer hybrid option), braking could be more responsive, servicing at Cadillac dealer is excessively expensive.
