Who we are
Owner-operated.
Sydney-wide.
RSG Mechanical is a locally operated mobile mechanic providing reliable vehicle servicing, mechanical repairs and 24-hour roadside assistance across the Macarthur region, Southern Highlands and Greater Sydney.
With a strong focus on honest advice and quality workmanship, we bring professional car servicing directly to your home, workplace or roadside — making car maintenance simple and stress-free. When you call RSG, you talk to the mechanic who turns the spanners, not a booking desk. That's the difference you feel in the price, the communication, and the work itself.
How we work
The standards
behind every job.
We show you the old parts
Every part we replace comes off the car and into your hands — you see exactly what was worn and why it mattered.
Upfront pricing, honest advice
You approve the price before a single bolt comes off. If something can wait, we'll tell you that too.
Quality parts & workmanship
Quality parts and oils matched to your vehicle, fitted with the same care we would put into our own cars.
Local & owner-operated
You deal directly with the mechanic doing the work — a local operator, not a call centre.
Straight answers
Things drivers
ask us first.
Do you really come to me — even just for a service?
Yes. Every job we do is mobile: logbook services, repairs and diagnostics happen at your home, workplace or wherever the car is parked. You keep your day; we bring the workshop.
Will mobile logbook servicing void my new-car warranty?
No. Australian law lets any qualified mechanic carry out logbook servicing using quality parts and oils that meet the manufacturer specification — your statutory and manufacturer warranty stays intact, and your logbook gets stamped.
What areas do you cover?
We're based in the Macarthur region and cover Gregory Hills, Campbelltown, Oran Park, Camden and Narellan, through to Picton and the Southern Highlands — Bowral, Mittagong and Moss Vale — plus the wider Greater Sydney area. Not sure if we reach you? Call 0419 678 242.
Are you really available 24/7?
Yes — RSG Mechanical operates 24 hours a day, every day. Breakdowns and emergency call-outs don't keep business hours, so neither do we. Call 0419 678 242 any time.
What if the repair is too big to do in my driveway?
Most servicing, brakes, batteries and common repairs are done on-site. For the rare job that needs a hoist, we'll diagnose it on the spot, give you an honest assessment, and help you plan the next step — no guesswork, no unnecessary towing.
How do I get a price?
Call us or send the quote form with your car's details and the issue. We'll come back with an upfront price before any work starts — and we stick to it.
What do you work on?
All popular makes and models — petrol and diesel, hatchbacks to utes. Recent jobs include Toyota, Hyundai, Subaru, Mitsubishi and Mercedes-Benz.
