Just drove in off the street with an engine warning light concerning me hoping they had the time to plug in diagnostics to identify any problems. What a lovely experience unfolded with the young chap at the counter. No problems, grabbed his diagnostics machine and walked me through the highlighted issues and even did a print out to take with me. Fortunately no major issues but he did spend 20 mins or so of his time with me and for no charge. I did donate to their men's mental health charity though. I live in Melbourne but spend some time in South Gippsland. Seriously considering getting my car serviced here in the future after this experience.

I came in with a curly wiring job on a late model Jeep, I don't dare play with the electrics and computers controlling the cars these days, but the guys were all over it. Kept me updated with possible computer/controller issues and workarounds, and had me sorted in no time! Great customer service, highly recommend, and will be back for all my 4wd needs!

Couldn’t be happier with the three times my vehicles been in to visit SG Wonthaggi. I had email dealings with Dave for at least a month while sorting out accessories for my 4wd. Countless emails and he always responded quickly and with helpful advice.
Quality of work was has been second to none, all while being completed almost exactly as per quote.
I had both electrical and mechanical upgrades done, and communication during the process was excellent for both.
Chris in auto electrical met with me the morning of booking, ran through layout and plan of attack and his professionalism made me very confident of a perfect result. They went above and beyond, even doing things that were not exactly in the scope of works for the day.
Couldn’t be happier.
