I was researching 2nd gen Buick Park Avenue Ultras, and ran across a forum posting where someone was describing problems they were having with the HUD in their 2005 model.
I didn't even know they had HUDs, so I tried searching more, but can't find any information that confirms or denies this. Haven't found any pictures showing one, either.
Does anybody know, was this standard, or optional equipment, and on which years?
