Japanese Vehicle Specialists in Kings Langley

Here at Japex Automotive, we’ve earned an unparalleled reputation in the Hertfordshire area over the years as a trustworthy and reliable Japanese car specialist, helped by our extensive experience and knowledge, use of authentic parts, and highly competitive prices.

However, we don’t just repair, service and maintain Japanese models, we work on most other makes and models too.  Our 5,000 sq ft workshop in Kings Langley is perfectly located if you’re looking for car and van repairs, MOT testing or vehicle servicing in Watford, Hemel Hempstead, and surrounding areas.


Our team of technicians has over 100 years combined experience working on most makes and models, with particular expertise and interest in VAG, Mercedes Benz, BMW, and Ford models as well as Japanese models. In addition to our  experience and skills working on standard fuel vehicles, we’re qualified to work on electric and hybrid vehicles safely.  Further evidence of our expertise in this growing area of vehicle maintenance is our membership of HEVRA, which is a UK-wide network of vetted independent garages working on EV and hybrid vehicles.

We’re also the leading specialist engine tuning centre in Kings Langley, serving customers from all across Hertfordshire who come to our workshop to take advantage of our experience and expertise. In the last few years, we’ve become part of Avon Tuning’s network of Authorised Agents and we’re very proud of this association as Avon Tuning is the leading ECU remapping and performance tuning company in the UK.

Repairs and Servicing at Japex Automotive

As the area’s premier independent garage, we’ll assign you a mechanic who has the most up-to-date knowledge of your particular vehicle. Using the latest manufacturer’s specifications and dealer-level diagnostics they’ll ensure your car is repaired or serviced to the highest standard without affecting your warranty. Our knowledge and broad experience covers almost all makes and models and we’re always delighted to advise and/or estimate for work without obligation.

JDM (Japanese Domestic Market) Vehicles

Please note: if your vehicle is a Japanese import, as opposed to a UK-specification vehicle, we may not be able to source parts or diagnose problems due to specification and component differences between the two kinds of vehicle. Please call us or pop in to discuss your Japanese import with us and whether we are able to work on your vehicle.
