Agreed - built like a tank.
Many were refurbished and sold 'like new' in Denmark.

I don't know the current situation, but in the 1980s all vehicles were subject to 180% importation tax (there were no vehicles built in Denmark - all were imported). This meant that existing vehicles were cherished and it was worth spending significant sums on doing them up rather than spend on new ones. Even secondhand (used) vehicles were taxed when imported (and Danes were prohibited from driving non-Danish registered vehicles in Denmark - to prevent temporary importation of non duty-paid vehicles).

Still many 240/245 rolling in Sweden.

In Sweden it's not allowed for a swede to drive a car with a foreign plate.
And if I move to Norway I'm only allowed to have my car for a year. Then I must get special permission. Or get a norweigan license plate for it...
