Busso Engine பராமரிப்பு:
Timing belt maintenance is paramount. Potential for oil leaks from valve covers and seals. Head gasket integrity is important. Overheating can be an issue if cooling system is neglected.
Electrical Gremlins:
As with many Italian cars of this era, electrical issues can arise due to aging wiring, connectors, and components.
Transaxle Issues:
Wear in the shift linkage or potential issues with the rear transaxle seals or bearings if neglected.
