I got mine about 3 years ago (gave my otg to my boys). I think mine had been used only a few times since the PO had it. Took it home and gave it a good cleaning, was just like new. Now I am afraid I need to clean it again as it has had lots more cooking.
Weber service is the best, when I was cleaning mine I lost the clip which held part of the burner together. Called Weber and they could not find one to send me so they sent the whole hardware pack.
Great grill hope you have lots of good times
