Here in Finland I can't ever register a modified fiero, or any cars. If U chop the roof, the car never get road legal etc.. Only way here to get the car road legal, is to use custom chassis, and make 1 car for personal use.. If make 2 or more, then need crash test etc.. But 1 cat, with custom chassis, it is possible.. Its because of that E-proof, or how to say it in english, not sure.. but because of it, nothing what is structural in car, can't be changed.
