In Sweden when a car gets 30 years old, you don't have to pay tax for it any more (only 4 Euros per year to get the taxsticker) also you only have to take the car to the vehicleinspection every two year instead of once a year.

If the car is from 1950 or older you don't have to go to the vehicleinspection at all.

You can also get a very cheap insurance from carclubs for your old car but then it have to be in perfect condition and you can't use it as dailydriver.
