“ A chance to buy a fun and reasonably priced British classic. ”

With its practical coupé body, robust mechanicals, and unleaded fuel conversion this MGB GT offers an accessible and enjoyable route into classic car ownership.

Background

The MG marque has long been synonymous with the accessible British sports car. From the 1920s onwards, the company built its reputation on producing machines that combined engaging performance with affordability, opening up the thrill of open-top motoring to a broad audience. By the time the MGB was unveiled in 1962, MG had already established a formidable pedigree with cars such as the T-Series and the MGA, both of which proved popular on home soil and across the Atlantic. The MGB was, however, a significant leap forward.

Where the MGA had relied on body-on-frame construction, the MGB was designed around a monocoque chassis, making it lighter, stiffer, and more refined. This shift mirrored broader trends in the automotive industry but was particularly noteworthy for a relatively affordable sports car. It gave the MGB a degree of sophistication that was unusual for its class and price point, ensuring that it was more than capable of competing with rivals from Triumph, Sunbeam, and even Alfa Romeo.

The styling was another strong point. With clean, modern lines penned in-house at MG, the MGB looked contemporary yet understated, and it remains one of the most recognisable British sports car shapes of the 1960s. Initially offered as a roadster, it was joined in 1965 by the fixed-head GT. Styled by Pininfarina, the GT featured a distinctive fastback profile with a large opening rear hatch, effectively creating one of the first true sporting hatchbacks. The result was a car that retained the nimble character of the roadster but added all-weather usability and additional practicality.

Mechanically, the MGB remained true to MG’s formula: robust, simple engineering that could be maintained by enthusiastic owners without specialist equipment. The 1.8-litre four-cylinder engine, producing around 95bhp, provided lively performance, while the use of rack-and-pinion steering and front disc brakes gave the car handling precision and braking capability superior to many of its peers. The GT variant carried only a modest weight penalty compared with the open car, so performance remained spirited, and the coupé body made it suitable for long-distance touring in a way that few rivals could match.

The MGB was not only a domestic success but also an export phenomenon. A large proportion of production was destined for the United States, where the car tapped into a growing appetite for small, affordable European sports cars. In total, more than half a million MGBs were produced between 1962 and 1980, making it one of the most successful sports cars of all time.

Today, the MGB GT stands out as a particularly versatile and usable classic. It retains all the charm of the open car but offers the added practicality of an enclosed body, making it a year-round proposition for enthusiasts. Its straightforward engineering and excellent parts availability make ownership refreshingly easy, while its enduring style and historical significance ensure that it remains highly collectible. For many, the GT represents the sweet spot of the MGB range: stylish, practical, and quintessentially British.

Overview

The example offered here is an MGB GT that presents as a straightforward and usable classic, enhanced by a number of sensible updates. Most notably, the cylinder head was converted to run on unleaded fuel in 2020. More recently, a new starter motor has been fitted.

The car gives the impression of one that has been used, cared for, and maintained as an ongoing part of an enthusiast’s life, rather than as a static display piece. It sits as a car ready for continued enjoyment, offering its next owner the chance to experience the MG driving character in a practical coupé body.

For collectors, the appeal of the GT lies in its unique balance of usability and style. It is at once instantly recognisable as an MG, yet also slightly more practical than the open roadster thanks to its Pininfarina-styled roofline. For drivers, it offers a level of versatility that few classics can match — equally at home on a weekend B-road jaunt, a continental tour, or simply as a dependable entry point into historic motoring.
 

Exterior

The GT’s fastback bodywork remains one of its most appealing features, its proportions instantly recognisable and distinctly Italian in influence thanks to Pininfarina’s hand. With its sloping rear window and compact stance, the B GT manages to combine the charm of a traditional British sports car with the practicality of a small coupé. In many ways, it prefigured the concept of the modern sporting hatchback.

The paintwork and body panels present with a tidy and honest appearance. While detailed inspection in person will reveal the finer points, the overall impression is of a car that has been looked after rather than neglected. The paint retains an even finish, the panel fit looks consistent, and the car carries itself with the kind of confidence that comes from steady use.

Chrome trim and brightwork show well, providing the appropriate period sparkle without appearing over-restored, although the large rubber bumpers would perhaps benefit from some Back To Black or similar, to restore their sheen. Some of the rubber window seals are starting to fail.

Generally, everything matches the car’s overall presentation: clean, usable, and authentic. The alloy wheels (from a Limited Edition MGB) further reinforce its purposeful stance, and the car presents as a cohesive whole.

The B GT’s exterior design has aged remarkably well, its lines still admired six decades on. As a car to be seen in, it strikes exactly the right note – classic and stylish without being ostentatious.
 

Interior

The cabin of the MG B GT offers a pleasing mix of practicality and period charm. With seating for two in comfort and additional space in the rear for occasional passengers or luggage, it makes for a surprisingly versatile sports car, bridging the gap between a compact coupé and a practical touring car.

The dashboard layout is simple and functional, with clear Smiths instrumentation and straightforward switchgear. Its classic twin-dial arrangement places speedometer and tachometer directly ahead of the driver, while secondary gauges provide vital information in a neat row across the fascia. For many enthusiasts, it is this functional honesty that defines the B GT: everything is clear, unfussy, and ready to be used.

The overall condition appears consistent with a car that has been used but cared for, providing a sense of authenticity rather than the overly fresh feel of a retrimmed interior, although the owner has fitted leather seats. The door cards, and trim retain the character expected of a car of this age, and the general impression is one of a cabin that has aged gracefully.

Practicality was one of the GT’s strengths, and that remains evident today. The rear hatch provides access to a useful luggage space, making the car a realistic proposition for touring or longer trips. The rear seats are compact but serviceable, especially for children or occasional use. In total, the interior reminds us that the B GT was never a flight of fancy — it was intended to be lived with, and it remains so today.
 

Mechanical

At the heart of this B GT lies the familiar 1.8-litre four-cylinder engine, long admired for its robustness and tuneability. In 2020 the cylinder head was converted for unleaded fuel, ensuring ease of use with today’s petrol and making the car more practical for regular enjoyment. This is a particularly worthwhile upgrade for anyone intending to cover mileage, as it eliminates the need for additives and preserves the engine for long-term use.

The engine bay itself is reasonably tidy and looks original, save for an alloy rocker cover.

The rest of the drivetrain, comprising a four-speed manual plus overdrive gearbox and rear-wheel drive layout, remains as straightforward and enjoyable as ever. The B GT was never about outright speed but rather about balance, responsiveness, and character. Even today, the way it flows along a twisting B-road or settles into a steady cruise on an A-road remains engaging.

Looking underneath we did spot some corrosion on the offside sill, and as ever, we advise all potential bidders to come and see the car for themselves. As always with an MGB, the availability of parts and specialist support means that future upkeep should be straightforward and affordable.

The owner says the handbrake switch is faulty which brings a light on on the dash, so the bulb has been removed, and that the rear left indicator bulb failed during the trip to Bonhams.
 

History

The MG comes with a selection of historic invoices and a pile of old MoT certificates, although, of course, being over 40 years old it’s no longer required to be presented for an annual test.

The owner bought it from a private seller in Oxfordshire after admiring it from afar for six months. Finally the owner upped sticks and moved to France, and the GT became available. He thinks the first owner passed it on to one of his children. He says:

‘I’ve enjoyed taking it to the south Devon coast many times, and London visits, as ULEZ does not apply to a classic car. It drives well, last year it had a new exhaust fitted, and each year I gave it a full service.’
 

Summary

With its practical coupé body, robust mechanicals, and unleaded fuel conversion this MGB GT offers an accessible and enjoyable route into classic car ownership. For those seeking a car that can be driven and appreciated without complication, it presents a tempting opportunity.
