I really enjoy driving the Envoy. I feel the handling is great, and it is very quite inside when the windows are up. The ride is smooth, and love the v8 for acceleration. The only faults on the interior are the clock is too small, and it's hard to get to the cup holder above the gear shift on the console. I love the room in the back, but I wish the seats folded down a bit flatter. I love the idea of the built in air compressor.
The navigation system and of course OnStar.
You should be able to customize the display to show a larger clock.
