I think it was a GMC Envoy commercial from when the vehicle was first launched. It had two men driving in an Envoy, with the radio news talking about miraculous things that had happened that day. When the men get out, you can see their wings hanging under their jackets - they're guardian angels. One says, "So, do you always drive?", and the other says, "Yeah, I hate flying." The idea being that driving the Envoy is way better than, say, using your wings to fly if you're an angel. Does anyone remember this commercial and know where I can find it??
