After owning many other cars, incl. a Mercedes C230, my Buick Rainier is by far my favorite car, maybe ever. I'm in my early 30's, and a few years ago I probably would have scoffed at driving a Buick. In 2011 we were looking for a work SUV for my hubby (trailblazer, etc) and came across it at a dealership and got it for a steal. The next year he bought a truck, and I happily took over the Rainier. It is so comfortable, air ride is fantastic and it drives great. We got an extended warranty and had to have some of the suspension fixed (airbags and sensors) right after we bought it, but really no issues since. Have taken it on several long trips and it's just so comfortable! Really a great SUV.
Great gas mileage for an SUV, Leather Seats, Bose sound, air suspension, roomy rear cargo... I could go on and on. Reliability, this car gives me no issues and after spending a fortune maintaining a Mercedes, this really is one of my favorite things about my Buick.
Maybe a little more get up and go or improved handling, but really can't complain.
