2005 Z71, 207,000 miles. Seems if you keep throwing parts at them and catch problems early with keen ears and eyes, they'll GO, and GO and GO until mother nature reclaims them. (New England winter rot) Still on original hard brake lines, but they look awful and can go anytime.
I'm sure there's more, but off the top of my head...(in relative order, many aftermarket)
