Jaguar C-Type Problems Common Issues and Repair Costs
The Jaguar C-Type, officially known as the XK120-C, was produced between 1951 and 1953 as a lightweight racing version of the Jaguar XK120. It is world-famous for its aerodynamic design and for winning the 24 Hours of Le Mans twice. Today, the C-Type is one of the most collectible and valuable classic cars in existence. With only a small number of originals ever built, most cars on the road are either preserved originals or carefully crafted continuation models.

Long-Term Ownership and Reliability
The Jaguar C-Type is not a car for everyday use but a historic collector’s item. Owners act more as custodians than drivers, preserving its heritage. Even routine maintenance is costly, with annual servicing often between £5,000 and £10,000. Full restorations can run into six figures.
While expensive, proper maintenance is crucial to preserving both the car’s value and its ability to be driven on track or road.
