How can I tell if my Buick has AWD?

I recently bought a 2006 Buick Rendezvous. There's no user manual, it doesn't say anywhere on the car, and the experian autocheck report does not mention the drive-type. It does say on the back that it is a 'gold-edition' which I think just explains the gold buick logo on the front and nothing else.The guy I bought it from is not sure either. It's a 3.5L SFI, Not sure if it's CX or CXL. Thanks for your answers.How can I tell if my Buick has AWD?Lay down on the ground and look at the rear. You should see the rear CV shafts going to the center of the rear wheels on the AWD. Nothing on the FWD's.
