What We Do

Servicing & repairs, done the honest way

Whatever your car needs, Simon's seen it before. Here's what we handle every day.

Logbook Servicing

Keep your new-car warranty intact without paying dealer prices. We service to your manufacturer's schedule and stamp the book, so you're covered.

General Service & Repairs

From oil and filters to the full once-over, we'll keep your car running smoothly, safely and reliably — whatever the make or model.

Vehicle Diagnostics

Warning light on? Strange noise? We use proper diagnostic gear to find the real cause fast, then tell you straight what needs doing.

Brakes

Squealing, grinding or just not feeling right? We inspect, repair and replace pads, discs and the lot — because brakes aren't where you cut corners.

Clutch & Transmission

Slipping clutch or dodgy gear changes? We handle clutch and transmission repairs to get your drive smooth again.

Suspension & Steering

Clunks, pulling or a rough ride? We'll sort your suspension and steering so the car handles the way it should — and keeps you safe.

Auto Electrical

Batteries, starters, alternators and the gremlins in between. We track down electrical faults and put them right.

Pre-Purchase Inspection

Thinking of buying a used car? Let us check it over first — we'll tell you honestly whether it's a good buy or a money pit, before you hand over a cent.

About

Meet Simon — the "Slim" behind Slim's Garage

Simon's been fixing cars for 35 years. In that time he's seen every make, every model, and just about every trick in the book — including the dodgy ones other workshops pull. That's exactly why he does things differently.

Slim's Garage was built on one simple idea: treat people the way you'd want your own family treated. Tell them the truth, charge a fair price, and do the job properly the first time. No jargon, no upselling, no talking down to anyone.

Turns out, that goes a long way. Simon's hard work and honesty earned him the Leader Small Business Award — voted Melbourne's Favourite Mechanic by the people who matter most: his customers.

Good to Know

Frequently asked questions

Will a logbook service at Slim's void my new-car warranty?

No. Under Australian Consumer Law you're free to have your logbook servicing done by any qualified mechanic — it doesn't have to be the dealer. We service to your manufacturer's schedule and stamp your logbook, so your new-car warranty stays fully intact.

It depends on your car and what it needs. We'll always give you an upfront, honest quote before any work starts — no surprises.
