I have owned this for just a couple of weeks and have decided that this is one fine vehicle. Good acceleration and very acceptable gas mileage for its size. The ride is very good. Seats are very comfortable though the 3rd row seat could only accommodate a large adult in the middle seat. The two outer seating position would have to be for smaller adults or kids. All the bells and whistles work great. Plenty of storage area with ac jacks for a game or other brought from home device. If you need to seat 6 or 7 and want something in a very nice and luxurious crossover I can highly recommend the Enclave.
Backup camera/Nav system, bluetooth, air conditioned seats, articulating headlights, remote starter and Onstar.
The only thing I could really think of would be an active cruise control which would slow you down if a slower car is in front of you until the way is clear again and then bring you back up to your originally programmed speed.
