Jason spent alot of time investigating a problem with my mum's car which was revving at times at a frightening level, but only intermittently. The car was bought from a car yard and despite taking it to them a few times to find and fix the issue, they failed. My mum then took the car to two mechanics in Bendigo who again failed to find the issue and barely tried. When I asked Jason if he could investigate he took the challenge on and said he would find the issue no matter how long it would take. And he did! It was the throttle body. Now the car runs very nicely and Jason did a follow up check to ensure the car was well and truly fixed. Thanks Jason!

Finally - A garage that wants to spend time talking to you about your actual car! Jason explained everything, answered my questions, worked with me on a list of things that we sorted into must do / should do / don't bother. They have the tools and knowledge to get into the engineering of your car, not just a service or parts swap-shop. Ever had a GP visit where you get minimal time, can only discuss 1 item and they bill you with a script you're not sure you needed? That's the other guys... I've honestly wasted time and money with main dealerships and had mistakes made with other garages. Suspension, tyres, brakes, plugs, engine de-carb and 4 wheel alignment... 140K Km car feels like new on the road. Jason sourced parts and fitted some of my own - Overall great pricing and communication. Happy new customer!

I needed a RWC with only a few days' notice and was very glad when Jason found a spot to fit my car in. Did great, and fair price charged for the work it needed.

Had a great experience with Jason. I had car troubles where I couldn’t turn my car off because the keys were stuck in the ignition in the evening. He was fully booked at the time and He still took it out of his way to come help me. His great customer service was fantastic, and was very happy to help someone in need. I would highly recommend seeing Jason for any car troubles.

I can't recommend Startamotive Sunbury highly enough. After a disappointing experience with a service at a local dealership, I had completely lost confidence. Thankfully, Jason and the team restored that trust. They took the time to listen to my concerns, explain everything clearly, and genuinely cared about getting my car back to the condition it should have been in. The service was professional, friendly, and transparent from start to finish. I can feel the difference! If you're looking for an honest, reliable mechanic in Sunbury, I wouldn't hesitate to recommend Startamotive. I'll definitely be returning for all my future servicing.

Couldn’t recommend Jason and his team highly enough. Jason is genuinely passionate about the industry and takes a lot of pride in what he does. He’s fantastic at explaining things simply and clearly, and always gives you plenty of options and ideas, explaining the pros and cons so you can make an informed decision. The whole team is friendly, knowledgeable and clearly takes pride in their work. It’s hard to find a mechanic you can completely trust, but I wouldn’t hesitate to bring my vehicles here or recommend them to family and friends. Great people, great service and a team that genuinely cares about what they do.

Highly recommend Jason, I got a pre-purchase vehicle inspection and he was fantastic! His inspection was really thorough and detailed, and his advice was considerate, clear, and extremely helpful!! Organising everything was super efficient and he was very reliable and professional!
