A real truck with real towing capacity, yet as quiet and smooth as most luxury cars in town and on trips. Optional sound system is very good. The nav system in my 2004 was cumbersome, so we left it off the new 2007. Buick fixed the AWD system, and it engages smoothly in 2007. Competent handling for a luxury truck. Don't drive or evaluate it as a sports sedan. I used to make jokes about people who drive Buicks, but this vehicle grows on you.
The 2004 Rainier that I had rode a lot quietier. This 2007 has a wind noise starting at 35 mph and gets louder. I have had it back to 2 different dealers for this problem as suggested by GM motors. They can doing nothing at this time because of no recalls or service bulletins. It seems to me that it is the door seals on the back. Sounds like the back window is open a little on both sides
We were looking at the Acacia when the dealer showed us the Rainier. The value for the Rainier was exceptional. We towed our boat on a 2,000 mile excursion through the Sierras and it pulled with very little problem. Comfortable seats, quiet and smooth ride. The fold back rear seat headrests help with vision when no one is riding in the back. The built in air compressor is a plus. urning radius is very tight.
