2005 3/4 gone...dealer is terrible about updating advertisements.

now its a 2005 LS 1500 with 70K and 3 cloth, bench seats. I like the idea of being about to pull eveyone up to the front seats if needed to make room for hauling. I took it for a spin last night. There is a some issues the the dealer will have to address bfore I bring her home. The engine has some lifter noise, the front right caliper is dragging and making it pull to the left and the air bag service light and reminder is on. the body is in excellent shape and everything else seems to be working as it should. One more thing...there is not a VIN ID tag on the drivers door. This has me concerned. Do not suburbans have that ID tag on the door or door jamb? With the ID tag gone (?) and the air bag light on, could the vehicle have been wrencked with out it showing up on the CarFacts?
