"Many non-commercial vehicles (both auto and truck) have exceeded 1,000,000 miles (1,600,000 km). For instance, in 2013, East Patchogue, New York resident Irv Gordon (1940-2018) had accumulated 3,000,000 miles (4,800,000 km) in his 1966 Volvo P1800. The car had amassed 3,200,000 miles (5,100,000 km) by Gordon's death on 15 November 2018." https://en.wikipedia.org/wiki/Car_longevity https://autos.yahoo.com/news/the-first-car-to-3-million-mile...

Honestly, I'd not use the word many, perhaps a significant number....
