They would make great starting projects for aspiring Car restorers.
Both look relatively operational so I wouldn't be so hard to get them running. I've seen cars in daily use that looked far worse.
My classmate bought a rolled 1956 (i think) Bel Air that had been parked in a Nevadan barn since the early sixties. Took less under 30 minutes to get it running well enough to drive around the block.
The bodies seem in rough shape. I am pretty sure that a person would have to replace the interior. The outside needs to be sanded down and a new primer and paint put on it. The green one looks in worse shape, but the other one needs work as well. I would think that both probably need work(engine, transmission), they look like they've been left outside for too long.
Mate, the word "operational" is relative. I'm not saying its gonna pass an MOT anytime soon. For a mechanic, operational means the engine turns over and the car is drivable short distances.
Cars that have been parked in dry areas for longer periods of time, tend to start and be drivable onto a tow truck and back into a workshop for instance after minor repairs.
EDIT: We have a A B C system at work.
A1 Passed MOT
A2 Failed MOT, but drivable. (Minor issues)
B1 Crucial repairs but running (drive train issues, braking system failure. )
B2 Crucial repairs, non running (Non running engine/ non working transmission)
C1 Restoration project (Repairable)
C2 For parts (Non repairable)
