My best friend has a 58 long bed fleetside that he got when it was one year old and drove to work and back, 120 miles, 7 days a week for over 25 years. This comes up to over a million miles. He still has it and it looks like it has closer to a thousand miles on it. He wore out the 235, overhauled it and wore it out again, went to a 327 and wore it out several times. Steering, brakes, rear end, everything except the engine is just the way it came from GM but of course with several service replacements. He is a nut on maintenance and rebuilds or replaces things at the first sign of wear rather than let it go till it breaks. He did go to an alternator several years ago when generator parts started to get very pricey. He's 80 years old now and I wish some reporter type would run a story about his old truck. I think the answer is, yes, they can be driven every day just the way they came new.
