I know of MANY caprice LT1's that have passed the 300k mark, and many many in the 200k - 300k that are raced hard. It's all about matinace. My dad drives 4-5 96 9C1 cruisers, That have 175k, 200k, 230k, and anouther around 200k-ish, not sure on the 5th one, if there is a 5th one. My dad says they all still burn the tires at a stoplight, never burn oil, never give him crap(engine wise). about a week ago, he had the 230k one, doing 85 on the highway, and the Torque converter blew up. the Engine is not the weak link. The caddy had about 160k when it found the tree, and the caprice has about 180k. I know of a few guys who spray them at 175k... whats that tell ya?
