mileage on your car

My 75 Valiant has 38,000 original miles on it. My 77 Aspen is showing 10,000 on it, driving it feels like 110,000 but sitting in the drivers seat feels like 210,000, it doesn't burn any oil so my guess is 110,000 and that a fat guy was the main original owner. My 78 Adventurer has 88,000 original miles and my 95 2500 Cummins has 220,000 on it. I won't go into the 2 Dodge trucks I retired.
