Both of my folks have been smokers since their teens. Starting in his mid 40’s, dad has had three heart attacks, three stents placed, and a triple bypass. No one expected him to still be alive. But his car was always clean. Emptied the ash tray as soon as he got home, every Sunday the glass got Windexed and the car got vacuumed.
Mom is 74, still driving the '75 Buick she bought new. Her car was always a no-smoking zone. Maybe on a long road trip you could light one if there was no rest area near by, but to this day you can get in the car and still have that 70’s GM smell.
