Few cars encapsulate the spirit of classic British open-top motoring quite like the MGB Roadster, yet examples such as this occupy an altogether rarer place in the marque's history. Originally Bronze, it is thought to have been repainted in its striking factory-correct Primrose Yellow with black vinyl interior at the time of the conversion. This 1971 MGB is not simply another chrome-bumper Roadster - it is one of an exceptionally small number professionally converted from new specification into a genuine 2+2 by the renowned Befour Conversions.

Believed to be one of only around 20 examples completed, this highly unusual conversion transforms an already iconic sports car into a remarkably scarce collector's piece. The additional rear seating has been executed with period sensitivity, preserving the unmistakable profile of the MGB while creating one of the rarest derivatives of the model. Opportunities to acquire a Befour-converted MGB are exceptionally infrequent, making this a fascinating addition to any serious British classic collection.

Power comes from the proven 1798cc B-Series engine, driving beautifully through the gears and offering the engaging character for which these are celebrated. Vendor research suggests it is fitted with the desirable Gold Seal replacement engine, a sought-after period feature, although this has not been independently verified.

The MG was acquired by its current owner in 2023 from a long-standing family friend who had cherished it for more than 35 years before ill health sadly brought his ownership to an end. Believed to have been only the second keeper from new, this impressive continuity of ownership speaks volumes about the affection and care this rare MGB has enjoyed throughout its life.

Accompanying the B is a substantial history file containing invoices, period paperwork, and photographs documenting both the remarkable Befour conversion and the long-term ownership history. This provenance significantly enhances its appeal and provides valuable insight into its unique story.

Further investment has been made in recent years, with less than 300 miles covered since extensive recommissioning work in 2023, including the fitting of a new clutch, refurbishment of the front crossmember, overhaul of the front braking system, and installation of electronic ignition, ensuring it is ready to be enjoyed by its next custodian.

As expected of an example now approaching 55 years of age, the paintwork displays a pleasing level of honest patination, with some age-related imperfections including areas of paint crazing and slight variation in colour across the upper sections of the front wings. The body itself appears reassuringly solid, allowing the rarity and originality to remain the defining features.

Adding a further layer of desirability is its highly distinctive registration number, a memorable and individually valuable asset that only enhances the individuality.

Rarely does an MGB offer such a compelling combination of rarity, provenance, long-term ownership and usability. As one of the handful of known Befour 2+2 conversions, this represents an exceptional opportunity to acquire one of the most unusual and collectable variants of Britain's enduring sporting icon.
