What We Do

We’re a small workshop based in Sydney, passionate about cars and even more passionate about doing right by our customers. Whether it’s your daily driver or your weekend project, we treat every vehicle like it’s our own. No upsells, no dealership markup — just quality work at a fair price.

Our Services

Auto Maintenance Services​

We offer logbook servicing, general services and checkups. For a quote, ring us anytime during business hours and let us know what service you would like done!

Brake, Tyre, Battery and Report

We offer a free brake, tyre and battery report with every service you do with us, including rough estimates of how long each component will last before needing to be replaced for peace of mind.

Repairs

At Deadly Customs, we handle all major and minor car repairs — including engine, transmission, brakes, steering, driveline, audio systems, cooling, electrical faults, air conditioning, and exhausts. We use quality parts, get it right the first time and are in touch with the best specialists in Sydney so you can drive with confidence.

System Diagnosis

We offer a no solution, no charge policy for all diagnostic services. If we can’t identify the issue or provide a clear solution, you don’t pay a cent — it’s that simple. We believe this is how all workshops should operate: with honesty, transparency, and respect for your time and money. Our goal is to build trust, not charge for guesswork.

Customer Testimonials

I took my car to Sean after taking it to 3 other mechanics for a brake problem. All three other mechanics couldn't figure out the problem. Sean quickly found the problem and fixed it for a great price. I have been taking my car to him for the past 2 years now and have been incredibly happy with the service each time. I have recommended him to family members and friends because he is great at what he does! I wouldn't trust anyone else with my car. I can 100% recommend him to anyone looking for a high quality mechanic.

We've been taking both our Skoda and Mazda to Sean for a while now, and we honestly couldn't ask for a better mechanic. Sean is not only highly skilled and reliable, but he's also genuinely honest — a rare find these days. He takes the time to explain what's needed, never tries to upsell, and always goes the extra mile to help out. Whether it's regular servicing or unexpected issues, we know our cars are in good hands. One of the best mechanics in Sydney, without a doubt. Highly recommended!
