I purchased a 2004 Rendevous and this 2006 Rainier replaced it. I missed a couple of features from the Rendevous. There is no parking assist and it does not customize the radio and seat settings on the key fob like the Rendevous. It does have curb view on the rear view mirror, but the mirrors are smaller than the Rendevous. The Rainier feels more stable on the road than the Rendevous and is quieter. I am getting better mileage than with my old Rendevous.
Center console shifter. 10 way power seats. Glass opening on the lift gate.
Bigger mirrors, customized driver settings (radio and seats) on key fob, and parking assist.
