So my bosses wife had to get a lambda because she loves his Acadia. I we went for a ride in her new Enlcave and it seemed a little quiter. This thing was loaded, and I asked her if she had HUD because it had everything else. She said no because the windsheild is double insulated and HUD wont work. Was that the salesmen making a deal or is that true. If it is true, I have to believe that the Enclave is quiter. Anyways, we still love our Acadia and I feel bad for those who are having problems with theirs. We have over 14k on our 2008 now and the only prob is the lumbar broke...no big deal.
