Your local mechanic for Christies Beach
Christies Beach sits right on the Gulf St Vincent coast, and the vehicles around the Esplanade tell the whole story: daily commuter cars heading up Main South Road, and the towing and touring 4WDs that run south to the Fleurieu and Victor Harbor every weekend. As a mechanic Christies Beach drivers can count on, we look after both, close to home, without a trek across town to the city or the north-east.
Trusted Mechanical is a short drive away at 31 Aldenhoven Road, Lonsdale, so you get a genuine full-service workshop AND a real diesel-performance house under one roof. The everyday jobs (everyday car servicing that keeps your new-car warranty intact, brakes, suspension, air-con and batteries) sit alongside the specialist diesel work (diesel performance tuning, ECU remapping, dyno tuning and DPF cleaning), so Christies Beach owners do not have to split their car across 2 shops.

Everyday cars and serious diesel builds, under one roof
Most local workshops split the everyday car service and the serious diesel tune across 2 shops. We do both. That means a Christies Beach household can bring the family car in for a log-book service and the touring 4WD in for a custom tune to the same trusted workshop, with free loan cars on both so a day in the workshop is not a day off the road.
Getting to us from Christies Beach
Our workshop is at 31 Aldenhoven Road, Lonsdale, a short run from Christies Beach. Head up Beach Road and Sherriffs Road onto Main South Road, then into the Lonsdale industrial area off Aldenhoven Road. It is a few minutes up the road, not a trek into the city, which is exactly why so many southern-suburbs drivers come to us instead of heading north.
Drop-off is easy and free loan cars are available, so you are never stranded while we have your vehicle. We are open Mon-Fri 8:30AM-5:00PM, closed weekends.

4.8 stars across 302 Google reviews. It is the biggest trust signal the workshop owns, and it already dominates the diesel-mechanic results on Maps across southern Adelaide.
RAA Approved Repairer. RAA judges us on knowledge, skills and equipment, audits us regularly, and holds us to a fair-pricing promise: we will not charge you for work that was not done or was not needed.
We photograph your service and show you the photos when you come in. You see exactly what was done, even if you dropped the car before work and picked it up after.
An in-house chassis dyno means real diesel-performance capability, not just a service centre. And every job is backed by our 100% Result Guarantee, with all work fully guaranteed and free loan cars while your vehicle is in.
