Purchased the car with less than 10k on it and have put nearly 75k on it since then. The comfort and power are exceptional, as is the gas mileage. At nearly 24-28mpg, there is not another comparable vehicle even made today. No outrageous problems or issues with anything. It still turns heads and blows doors off of "wannabee's". Absolutely Awesome Ride. Hope to keep it another 10 years!
The Northstar, of course. Also, the comfort. It's like sitting in your favorite Lay-Z-Boy, but going 70mph.
The only thing that I wish Cadillac would have done was to add a few more 'cubby-holes'. You know, places to put stuff (iPod, Cellphone...).
