The Terraza rides great, has very comfortable seats, and drives very well. However, the driver's side sliding door rattles even after three attempts to the dealer to fix it. I have found the carpeting to be subpar for a Buick. It is extremely difficult, if not impossible to clean. I recommend Scotchgarding the carpet on day one. We owned two Chrysler Town and Country vans prior to the Buick. I must say the Chryslers were superior to the Buick, although the Buick rides better and has more comfortable seats. In summary - some aspects of the Terraza we really like and some we don't.
Ride, comfort of seats, great freeway cruiser.
Sliding doors need to be redesigned as they rattle and we have had both sides in to the dealershiop for repair.
