1970 MGB Roadster – Concours Restoration | 5-Speed Gearbox | £40,000+ Restoration

Just arrived at The Forge is an exceptional 1970 MGB Roadster, the subject of an extensive £40,000 nut-and-bolt restoration completed between 2021 and 2024 by renowned British classic car specialists Carn Bosavern Garage.

Originally supplied to the UK market, this outstanding Roadster underwent a comprehensive, no-expense-spared restoration with virtually every component either restored, rebuilt or replaced. The body shell was stripped to bare metal before receiving a stunning repaint in its current colour scheme, while the front and rear axles were removed, refinished and rebuilt with new suspension, steering and braking components throughout.

The restoration was carried out with usability and reliability firmly in mind, incorporating a host of carefully selected upgrades. These include a desirable Mazda five-speed gearbox conversion, electronic ignition, aluminium radiator, electric cooling fan, upgraded suspension, stainless steel exhaust system and numerous performance enhancements to the engine. The result is an MGB that retains all the charm of the original while delivering a far more refined and enjoyable driving experience.

The car presents beautifully both inside and out, with a striking specification that combines period character with subtle modern improvements. A premium Royal Blue mohair hood, custom leather interior, wool carpets, Moto-Lita steering wheel and integrated Bluetooth audio system further elevate what is already one of the finest examples we have encountered.

We acquired the car from a respected local collector whose carefully curated collection is known for containing only the highest-quality classic and sports cars. Having handled several exceptional MGBs in recent years, we can confidently say this example ranks amongst the very best.

Driving Experience

Today, the MGB presents beautifully and drives exactly as a properly restored example should. The fully rebuilt engine is strong, responsive and maintains excellent oil pressure, while the Mazda five-speed gearbox delivers smooth and precise gear changes. The upgraded suspension and braking systems provide a confidence-inspiring driving experience, and the car feels remarkably tight, refined and well sorted throughout.

Opportunities to acquire an MGB restored to this standard are becoming increasingly rare. Equally suited to long-distance touring, concours events, weekend enjoyment or inclusion within a serious collection, this outstanding Roadster represents one of the finest examples of Britain's most iconic sports car currently available.
