That 1985 Toyota emits more GHG and NOx per mile than a new vehicle because it wasn't built to meet the latest US or Canadian emissions standards. Older vehicles emit more pollutants so in some US states the government will buy the car to have it scrapped, thus improving the overall fleet emissions statewide. In California there are owners who keep and maintain pre-1975 vehicles because they have little or no smog control systems, are easy to work on, and they are exempt from mandatory bi-annual smog testing.
