Probably on Sundays the owners show them off on the streets of the city so that as many people as possible can see them, it is however interesting that even after 50 years since they were produced they still work😊

If well maintained, they can perfectly work. Although there are some restrictions, you know, in big cities (in their city centres) you can't drive cars that don't match some regulations about pollution...

You're absolutely right, if they don't meet pollution standards, they might not get them there, but these cars are still the pride of their owners.
