Not my mileage, but there is the Volvo owner who has logged 2 million miles in his 1965 P1800. Yes that's 2,000,000 miles on a gas engine. The engine was rebuilt once at the 630,000 mile mark. Volvo gave him a brand new car at the million mark, then another one at the 2 milion mark. That's over 54,000 miles a year for 37 years. The guy's name is Irv Gordon
