Modestly estimated at £32-38,000, the car had been discovered under a collapsed garage roof in 2002 and was then modernized with bills for a staggering £135,000.
The classic’s complete restoration included replacing the original engine for an XJ6 unit, fitting a five-speed automatic gearbox and a limited slip differential.
The braking system was also updated to four-pot callipers at the front, while the suspension was replaced with Gaz coilover shock absorbers.
The car’s interior suffered a similar fate with internals from the XJ and refinements such as remote central locking.
The exterior, though, was left ‘as was’ aside from being restored and finished in Cornish Slate grey.

A 1958 XK150 bettered its re-engineered compatriot selling on the day for £92,960 against an estimate of £72-82,000.
The Roadster had spent much of its life in the US before being shipped to the UK in ’92 when it was subject to an eight-year restoration, which included a replacement body by Contour Autocraft and a specialist retrim.
It was also given sympathetic modifications including power steering, electronic ignition, electric cooling fan, Coopercraft brakes and a new alternator.
