Rust And Corrosion:
Common for vehicles of this era, especially in areas with road salt. Key areas include wheel arches, sills, floor pans, and around window seals.
Carburetor Issues:
Carburetors can become gummed up or require adjustment due to age, leading to rough idling, poor starting, or fuel consumption issues.
Electrical Gremlins:
Age-related degradation of wiring insulation, connectors, and switches can lead to intermittent electrical faults.
Suspension Wear:
Worn ball joints, tie rod ends, and bushings can affect steering and ride quality.
Cooling System Leaks:
Aging hoses, radiator core, and water pump seals can lead to coolant leaks.
Fiat Legacy:
