COMMON FAULTS
Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles
Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.
The **Iso Fidia** is a rare and luxurious classic car, but like many older vehicles, it can have some common issues. Here are a few potential faults to be aware of:
1. **Electrical Problems**: Older cars often suffer from electrical issues, including faulty wiring and malfunctioning gauges.
2. **Rust**: Given its age, rust can be a significant problem, especially in areas like the wheel arches and lower body panels.
3. **Engine Issues**: The Chevrolet V8 engine can experience problems such as oil leaks, worn-out components, and difficulty starting.
4. **Interior Wear**: The leather and wood trim inside the Fidia can deteriorate over time, requiring restoration.
5. **Suspension and Brakes**: The de Dion rear suspension and drum brakes may need attention and maintenance to ensure safe driving.
Regular maintenance and care can help mitigate these issues.
