Opel GT (1968-73)

COMMON FAULTS
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 Opel GT (1968-1973) is a classic car with a few common issues to watch out for:

1. **Rust**: This is a major concern, especially in areas like the sills, floorpans, valances, and wheel arches. Pay special attention to the front wheel arches where there's a structural bulkhead.
2. **Oil Levels**: The 1.9-litre engine has a small three-quart sump, so it's crucial to regularly check and maintain oil levels.
3. **Electrical Issues**: Problems with the headlights and other electrical components can occur, often due to aging wiring.
4. **Starting Problems**: Some owners report difficulties with starting, which can be related to the carburettor or fuel pump.
