The Appeal

The V8-converted MGB has long been regarded as the ultimate evolution of the breed, marrying the B's elegant lines and nimble chassis with the effortless torque of a V8. Professionally converted in 2005 with a 4-litre V8, this example has been thoughtfully developed over the years into a well-sorted driver's car.

In the current owner's hands since 2019, it has been maintained by an ex-F1 engineer, with all major work documented in a comprehensive history file containing photographs and invoices. The vendor describes the car as a pleasure to drive: fast, comfortable, and well-suited to longer journeys with the roof down, and reports that it has been very reliable.
