The car is on display at the Geneva auto show to help the automaker celebrate the 50th anniversary of the XJ sedan, first introduced in 1968.

Jaguar said its Classic Works division in Coventry, UK spent 3,500 hours refinishing, replacing and redesigning more than 4,000 parts to create a car that McBrain refers to as his “ultimate” XJ.

While the car is based on a 1984 model, it incorporates a number of modifications to almost every aspect of the car.

The car is powered by a 4.2-litre inline six just as it was when it rolled out of the factory, but this one has three SU carburetors from an E-Type. Other mechanical updates include improved suspension components with adjustable rear dampers and 18-inch wheels housed in re-shaped wheel arches.

To this Series 3 car the Jaguar Classic team fitted Series 2 door handles and wing mirrors, and added modern LED headlights with halo signature lighting.

Inside, occupants benefit from extra sound deadening, improved door seals that reduce wind noise, modified seat cushions and uprated air conditioning. Other modern touches include a touchscreen sound system with backup camera and USB connectivity and remote power locks.

As a nod to the musical legacy of the car’s owner, the audio system’s control knobs were made to resemble those from a Marshall guitar amp, and the wood that trims the dashboard is sycamore, the material used to make McBrain’s favourite snare drums.
