Know of a few islands here and off Newfoundland where steel just about melts away, the islands are rather small and very open to the ocean, salt spray just about flies clear cross them during big storms.Some do.... some don't.....the older cars had more metal in them to start with and although subjected to salt air they are not subjected to direct attack from salt on the roads like mainland cars. Speeds are very slow and mileage very limited. And not all are mint.....many really beat but as there is no inspection they don't get sidelined like mainland cars...as long as it runs and you dare drive it you're good to go.....that's why it's so important that the miserable device be in excellent mechanical condition and the body secondary. There is no car ferry.......you have make arrangements with a private barge.....usually runs about $500 to get a car on or off......unless you can share with others and split the cost. I was lucky with the Saab.....we got married out there and had to rent a barge twice......once to bring the box truck over with the huge party tent and again to remove the tent......we didn't find anyone to help with the cost......the second trip, coming off with the box truck was my Saab, Steves 51 Dodge and a 6 cyl tow behind air compressor that Steve got for free because they couldn't get to run.......LOL Steve filed the points and she purred like a kitten.......SCORE!!!!!
Barging goods over and back would hit the pocketbook hard.
