It seems to me that as soon as you cross the border (like most Canadians, I live right next to it), the average age of cars on the road jumps 10 years. Here I very very rarely see anything from even the late-70s being used as a daily driver*, but just inside Washington boarder I see 40 and 50 year old trucks still being used as work vehicles and giant 70s land yachts with peeling vinyl tops still wheezing along.
Nothing pre-war though.


*I do see older vehicles, but they're all restored/collector types that only come out on sunny summer days.
