      A nice vehicle. I got the AWD function and couldn’t be happier. Plenty of room for the kids at an affordable price.

      To date, our experience with the 2026 Elevation has been excellent. The cabin is plush and extremely comfortable. The ride is vey smooth and although many critique the power train, we have found the AWD version to be more than adequate. The price is competitive and the entry version can be well optioned. The only negative we have is there is not an upgraded stereo. That said, the existing one is okay and can be set to individual preferences. The tablet looks a bit intimidating but is actually quite user friendly. So far we are more than pleased.

      I upgraded my 2013 Terrain to a 2024 Terrain. Lots of bells and whistles, still trying to figure out everything. Rides nice.
