At SUMIYAKA our specialty is Japanese Prestige and Performance cars. We offer the very highest standard of service to any owner wanting only the very best for their pride and joy, without compromise. Our years of experience, combined with the specialist knowledge and skills our team have gained in Motorsport and the performance automotive industry, make SUMIYAKA perfectly suited to the challenges of working with modern high performance cars.

SUMIYAKA have a big advantage over most of our competitors, because our background is based in Motorsport engineering which goes far beyond the scope of normal mechanics. Our commitment to excellence also extends to our apprentices, who attend the National Colledge for Motorsport at Silverstone, where they gain in depth knowledge of every aspect of performance engineering and vehicle maintenance, to a level well beyond normal mechanics training.

SUMIYAKA offer a very personal service to our customers, making every effort to surpass expectations in everything we do. Fortunately because of our knowledge, experience and facilities we are able to offer far more services than most of our competitors. Like most of our competitors SUMIYAKA can provide off the shelf options for your car, but unlike most of them we can also provide in house bespoke manufacture of custom parts. In fact anything from a bracket to a custom built turbo and beyond, all made to your own requirements.

Because of our love for the Mitsubishi GTO/3000GT, combined with our years of experience mantaining and modifying them; SUMIYAKA probably has more experience and knowledge of these cars than any other company in the UK, including Mitsubishi, we can provide everything you need to keep your GTO/3000GT on the road to the highest possible standard.

So whether you just need a service; have something special in mind, or you want full competition preparation, don't take a chance with your car- let the experts at SUMIYAKA look after you.
