The Trusted Mechanical guarantee

When you are choosing a mechanic warranty Adelaide drivers can actually rely on, the question behind every other question is simple: will these people stand behind their work? Our answer is in writing. Every job we do is fully guaranteed. If something is not right after we have worked on your vehicle, you bring it back and we put it right. No argument, no fine print, no being made to feel like the problem.

That is backed by our 100% Result Guarantee, the promise the whole workshop is built on. It is a confidence statement, not a disclaimer: we do the job properly the first time, and we own it if it is not. You never have to wonder whether you have been done over.

It is also backed by the RAA fair-pricing promise: we will not charge you for work that was not done or is not needed, and you are treated with courtesy and respect. More on what that audited credential means is in the RAA Approved Repairer section below.

The proof is in the 302 five-star reviews from southern-Adelaide drivers: the guarantee honoured in practice, not just on a page. Have a question about a specific job? Call the workshop and ask.

How long is my work guaranteed for?

Most workshops never publish this. We do, because transparent warranty periods are the clearest way to show we mean it. Whatever we carry out, you are covered for the workmanship and the parts we supply and fit.

  • Tunes and general servicing - you are covered for 6 months or 10,000km.
  • Brakes - you are covered for 12 months or 24,000km.
  • Driveline and transmission - you are covered for 12 months or 20,000km.

What the warranty covers

The warranty covers our workmanship and the parts we supply and fit, subject to the work being used as intended. A couple of honest caveats that protect you and us: an off-road delete tune is not warranted for on-road use, and an over-fuelled tune fitted without an exhaust gas temperature sensor can void warranty on related repairs. That is exactly why we tune the honest way and fit EGT monitoring.

These warranties apply across our diesel tuning and car servicing work.

RAA Approved Repairer: an independent stamp on our work

Our guarantee is not just the shop's word for it. As an RAA Approved Repairer in Adelaide, an audited third party vouches for the workshop. RAA judges us on our knowledge, skills and equipment, and the approval is subject to regular RAA audits. It is the strongest external trust signal we own after the reviews.

The approval carries a fair-pricing promise that matters to you directly: we will not charge for work that was not done or is not needed, and customers are treated with courtesy and respect. It is the reason a first-timer can trust the place sight unseen, before they have met us or seen the workshop.

Free loan cars while your vehicle is being serviced

A day off the road for your vehicle is not a day off the road for you. A free loan car is available while we work, so you keep moving, get to work and run the day as normal. For a first-timer weighing up a free loan car mechanic in Adelaide, that is the friction taken out of the whole process.

The terms are short and honest. A loan-car form is completed and a current, valid driver's licence is required. Availability is subject to a car being free, so it pays to book ahead. This is meant to be helpful, not gatekeeping: let us know when you book and we will line one up for you.
