I suspect this has to do more with social circles than country. Obviously there are more people buying new cars, or else there wouldn't be any used cars for anyone to buy. I think the same is largely true in the US -- lots of people would never buy a brand new car, but there's also many people who would only buy a car brand new. The break down is probably 30/70 or 40/60.
