We have had Mercedes, BMW's and Lexus. Most recent a Lexus RX330. The Buick is every bit as good and is more comfortable. We needed more room and didn't want to give up MPG. Guess what? The Rendezvous is bigger and gets better MPG. 15% better. We stopped by the dealer just to take a look and were sold and bought it that day. Sold by the vehicle, not the salesman who was very low pressure. Buick should do a better job of getting the word out on this one.
Ride, interior quality, power of 3.6L V6. The CXL+ package has almost everything.
My only (very small) complaint is that when the car is in the garage the rear hatch opens so high that it hits the top of the garage door. I had to put a pad on the garage door.
