Jaguar XK-150 (1957-61)

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 **Jaguar XK150** generally shares common weaknesses with many British cars. Here are some key points to consider:

1. **Rust Problems**: Like other classic cars, the XK150 can suffer from rust. Pay attention to sills and rear frame extensions, as these areas are prone to corrosion.

2. **Overheating**: Keep an eye on the cooling system. Overheating can be an issue, especially during extended drives or in hot weather.

3. **Front Bodywork Damage**: The stock brakes are relatively weak, which can lead to front bodywork damage. Inspect the front end for any signs of impact.

4. **Check Door Gaps**: Poor door gaps may indicate rust or structural issues. Examine them closely during your inspection.

Generations/Trim Levels

For example, a trim level designated as “GL” in the UK might be labelled as “XS” in another country. Due to these regional differences, the information provided on this site pertains exclusively to UK-specific products.
