Obviously this is an important question so I just made some edits in the system to show what we're driving. Since I'm not driving anything at the moment (planning on being out of the country for at least 6 months per year for a few years) - mine says "nothing at the moment". But if you go here: http://gmcowners.com/gmc-forum/profile.php?do=editprofile
You can add your vehicle so that people know what you're driving when answering questions...
