JB Automotive is an owner-run car repair workshop at 125 Mungavin Avenue in Rānui, Porirua. The owner-operator is Johnny Bostock. The workshop does engine repairs, rebuilds and replacements, cambelt replacements, basic electrical diagnosis, water pump, suspension, brake, gearbox and general servicing work. It also does routine work such as oil changes. Bookings are made through the website, and payment can be spread over four instalments with Afterpay.
Customers quoted on the website praise the honesty, the clear explanations, the diagrams drawn to show a problem, and jobs finished early. One says the workshop is a two-minute walk from the train station, which suits people who work in Wellington. Another, who lives in Wellington City, went back to the workshop after a second fuel line failure.
