Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored 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 AC 428 Fastback Coupe, also known as the AC Frua, is a classic car with its share of common faults. Here are some issues that owners have reported:
1. **Overheating**: The engine can generate a lot of heat, leading to overheating issues, especially at high speeds or during extended periods of driving.
2. **Electrical Problems**: Some owners have experienced issues with the electrical system, including faulty wiring and problems with the alternator.
3. **Suspension Issues**: The suspension system can be prone to wear and tear, leading to handling problems and a rough ride.
4. **Oil Leaks**: Oil leaks are a common problem, particularly around the engine and transmission.
5. **Body Panel Fitment**: Due to the hand-built nature of the car, some owners have reported issues with the fitment of body panels.
Despite these faults, the AC 428 Fastback Coupe remains a beloved classic car for its performance and iconic design.
