The real Clark Forklift was the C-500 series from the 70's to early 80's and sold in great numbers, this series was responsible for establishing Clark as the leading forklift manufacturer in North America. Tough to work on and always minor oil leaks (somewhat like the Harley Davidson motorcycle) this forklift was always very dependable and strong. Thery are still out there in the used forklift market, but are now showing their age.
