Those old Volvo's are wonderful vehicles. Aside from the crumbling-wires issues they suffer from in their age today, they are quite literally TANKS. T-Bone resistant, not from "crumble zones" and fancy composite materials, but from raw steel.
These cars are like the SQ machines of today. Built like tanks, and probably drive like them too (Sorry - Snobby comment from the owner of a German automobile).
I saw a fair few meandering round while in Norway during the winter. All mostly rust-free.
Close family-friend has one - gets thrashed all the time, and still going after all these years! (Norwegian drivers are fun to ride with, to say the least. Its amazing that car hasn't fallen apart).
Whilst the miles are piling on, they are solid cars, and you can get them for pennies (almost) here in Australia. Very sparsely equipped (Oops, there I go again), but have held together well, especially when Aussie models from that time have all but disappeared completely, from rust and mechanical issues.
