I have 86,000 miles as I drive on sales calls from GA,NC,SC,OH,KY,WV and had owned/rented Buicks, Taruses, Mercuries, etc. This CTS is the most comfortable; and gas sipping at 31 - 33 mpg at 70 MPH al day! What galls me is how the researchers continue to ignor the CTS when comparing it to it's peers. I will stick with the 6 cylinder; but will get yet another CTS!
The ride and the sound system - make this fun to drive.
Apparently the rear end seals have a tendency to start leaking. My antifreeze thermostat blew back in Nov; but I consider that a fluke.
