Jaguar XK specialist

“We work across XK120, XK140 and XK150 models with a deep understanding of the subtle differences between them.”

Care for Jaguar’s original sporting cars

Copthorne Classics is a family-run Jaguar specialist with extensive experience across the XK range, including XK120, XK140 and XK150 models.

These cars mark the beginning of Jaguar’s post-war sporting identity. Defined by their XK engine, flowing bodywork and mechanical simplicity, they offer a very different ownership experience to later models – one that rewards careful setup, sympathetic maintenance and an understanding of how these cars were intended to be driven.

We provide complete care for Jaguar XK models, from routine servicing and fault-finding through to full restoration, engine rebuilds and long-term ownership support.

A specialist approach to early Jaguar engineering

The XK models require a different mindset to later Jaguars. Tolerances, materials and construction methods vary, and the way these cars perform on modern roads depends heavily on correct setup rather than outright modification.

Our approach is rooted in traditional engineering practice. Each car is assessed carefully, with attention to engine condition, cooling, braking and chassis setup, ensuring it performs as intended while remaining usable and reliable.

We work across XK120, XK140 and XK150 models in both road and competition contexts, with an understanding of the subtle differences between them.

Jaguar XK services

We offer a complete range of services for Jaguar XK models, all carried out in-house and tailored to the needs of each individual car.

Routine servicing and maintenance are essential to keeping these cars operating correctly, particularly where they are used regularly. Alongside this, we carry out full engine rebuilds centred around the XK straight-six – one of the most important engines of its era. Whether to standard specification or a carefully developed fast road setup, the focus is always on smoothness, reliability and correct character.

We also undertake full and partial restorations, including chassis, bodywork and mechanical systems, with detailed reassembly and finishing. Projects can be delivered in stages where required, allowing owners to approach restoration in a structured and considered way.

Specialist knowledge extends to carburation and fuelling systems as well as ignition, cooling and braking systems. Each is set up not only to function correctly, but to deliver the driving experience these cars are known for.

“We offer discreet upgrades always with the aim of improving reliability and drivability without altering the essential character of the car.”

Sympathetic upgrades and usability

While originality is often a priority with XK models, there is also scope for carefully considered improvements to enhance usability on modern roads.

We offer discreet upgrades where appropriate – particularly in areas such as cooling, ignition and braking – always with the aim of improving reliability and drivability without altering the essential character of the car.

For owners who wish to use their XK more frequently, these subtle changes can make a significant difference to confidence and enjoyment.

A workshop built around craftsmanship

All work is carried out at our dedicated facility, with in-house engine building, machining capability and restoration bays. This allows us to maintain full control over quality, from initial inspection through to final setup.

Many of the XK models we look after remain with us over the long term, with ongoing maintenance and refinement forming part of their ownership journey.
