Have been to look at a 74 3500s today, the car have been off the road since 86 with a siezed engine. On the outside all the panels seem good apart fron the front drivers wing, I've seen 5 year old cars with more rust. I have given the car a going over from the inside the car floors and inner sills seem solid the interior is in good order. the only place the screwdriver went through was under the car just in front of the rear wheels, around the bolt on each side uprights in the boot and the inner wing where the outer bolts on is gone about half its length. A mate at work has a 3.9 and 5 speed sd1 gearbox I can have for beer money. I know the brakes and bushes will need changing. the car will cost me £600 inc transporting, Is it worth it for a car that has been off the road over 30 years and what else should I look for?
