So much for the Modman....

no. you are right. actually such an old car has an historical tax Status. i pay approx 240 usd a year. if i go with this modern engine with modern induction the car looses this Status and is a modern car. i would pay ( if withould catalytic converter ) approx 1500 usd. Our laws are saying that the newest part on the car is maximum 10 years younger than the car itself. ( induction would have to be made latest 1982 in this case ).
So now please dont ask how i did it with the engine iteself.... :D
