My parents have a 2000 Silhouette for sale, well-kept. GM 3400. It has about 250k miles on it, but its all highway. They used to drive it out to Yellowstone and Montana and such on vacation in the summers. New struts and shocks all around, air shocks in the rear, full leather interior. Engine was replaced last year due to head gasket failure. I think they want to get 2000 out of it; not sure if crack-pipe, but it does ride nicely.
