About Mr J40
Specialists in Austin J40 pedal cars, driven by a passion for British motoring heritage, restoration and preservation.
A dedicated Austin J40 specialist
Mr J40 is a British specialist business dedicated exclusively to the Austin J40 pedal car.
Our work encompasses complete restorations, sympathetic repairs, replacement parts manufacturing, heritage documentation and the sourcing and sale of Austin J40 pedal cars.
What sets us apart is our focus on a single iconic model. Rather than working across a broad range of vintage toys or classic vehicles, we have developed our knowledge and experience around the Austin J40, its construction, history and restoration.
Our aim is simple: to support owners, collectors and enthusiasts in preserving these remarkable British pedal cars for generations to come.
Experience and approach
The story behind Mr J40 began with a long-standing enthusiasm for Austin J40 pedal cars and British motoring heritage.
Having grown up around these iconic pedal cars, our founder developed a particular interest in their construction, originality and restoration. The first personal J40 restoration project began at the age of 17, laying the foundation for the specialist work carried out today.
Over the years, this interest has developed into practical experience in restoration, component development, historical research and supporting fellow J40 enthusiasts.
Today, Mr J40 combines that enthusiast-led approach with a professional commitment to workmanship, honest advice and the preservation of original character wherever possible.

Authenticity and attention to detail
Preserving the character and history of the Austin J40 is central to our work.
Our approach is informed by surviving original examples, historical reference material and practical restoration experience. We place particular importance on appropriate finishes, components and careful workmanship.
Where original parts cannot reasonably be retained, suitable replacement components may be manufactured or supplied to support the restoration and continued use of these historic pedal cars.
Who we work with
We work with collectors, restorers, and enthusiasts in the UK and internationally. Some clients are long-term collectors, while others are first-time owners seeking guidance and reassurance.
In all cases, advice is practical, informed, and tailored to the individual pedal car rather than a generic process.
Our philosophy
Austin J40 pedal cars are historical objects as well as collectable items. Our aim is to preserve their character, accuracy, and longevity, whether through careful restoration, sympathetic repair, or informed ownership.
