Twin Spark Wear:
Potential for camshaft wear, especially on older engines, due to the 'twin spark' ignition system design (two spark plugs per cylinder).
Rust Corrosion:
Common for older vehicles, especially wheel arches, sills, and around windows. Underbody rust can also be a concern.
Electrical Gremlins:
As with many Italian cars of this era, some electrical issues can arise, often related to wiring harnesses, connectors, or relays.
Suspension Wear:
Worn bushings and suspension components can affect handling and ride comfort, typical wear items.
