This is the most responsive vehicle I have ever owned. The down side is, if you are not paying attention, you will be doing 80 mph and not know it. The ride is soft, yet sturdy. The steering is crisp and responsive. Gas mileage at 65 mph is in the 20+ mpg. As stated it's to easy to do 80 and that lowers mpg to around 17.5 mpg. Put a pinstripe above door handles and you have a great looking sports car that is tuff to get stuck in the mud or snow.
Acceleration, quick response, sound system, I have the gps and it is a must, comfort, (I am 6'3" and have plenty of head & leg room), visability.
It is missing some of the regular Cadillc frills, such as telescoping steering wheel, flashing arrows in side mirrors. That is getting pickey. The vehicle is a homerun.
