1947-1965 / Sedan / Sweden
The fuel tank rusts, internally or externally. Leaks, smell of petrol in the boot.
Age, condensation, ethanol fuel eating old tanks from the inside.
Replace the tank. You can get reproduction tanks or have the original re-sealed, but replacement is safer.

The top of the front wings (fenders) rust badly, especially above the headlights and around the indicator lights. The headlight bowls themselves corrode from the inside.
The sills rot, badly. All three sections, outer sill, inner sill, and the welded-in reinforcement, corrode together.
The front chassis legs (beams) and subframe corrode, particularly where the subframe bolts to the chassis. In extreme cases, engine mounts fail and the engine literally drops.
Doors rust at the bottom. Hinges sag or seize. Water sits inside the door skin.
The boot (trunk) floor and spare wheel well rust through. Fuel tank can corrode or leak.
