My Chevy truck is 82 years old. I have no idea how many miles she has under her belt. I too get lots of offers to buy. Maybe one day but I’m having too much fun to get rid of her just yet.
That has to be some kind of record. Older has always been better. I marvel that every time I use my 39 Ford 9N tractor that it starts up within 30 seconds, of course it gets a lot less use than my truck.
