I drove a forty one Chevy every day for a couple of years. It was about 20 miles one way. Part hyway and part city. It was all original.I didnt do anything to it. Just bought it and drove it. This was about 20 years ago. I traded it for 3 baby calves.Two of them died. Worst trade I ever made. Wish I still had that old truck. Stay off the freeways. Freeway drivers seem to be a little crazy around here.
