Very happy with the work they did on my car. Good quality products used. Very understandable and polite.

G-Force repaired the air conditioning on my car within the time period they promised and kept me informed as necessary.

Nathan was great, He managed to fit my car in to take a look at it and give me a quote, and then it was ready to be picked up by about 2 in the afternoon. All fixed. Nath, you legend, thank you, you have got all my business.

Great service! Transparent, efficient and as agreed. Highly recommend!

Friendly and helpful. The job was completed ahead of the estimated time.

Very friendly and completed the jobs as asked.

They went above and beyond for us I'll always be using and recommending these guys everywhere and telling everyone to use them and the price was fair.

Excellent service from Omid. Would use again.

Very easy to find a local car air-conditioning workshop. Knowledgeable and helpful mechanic. Job done earlier than expected.

Thanks Steve for sharing your experience!

Pleasant to deal with and very competent, my rego inspection was done quickly and efficiently. Clean and pleasant workshop and easily accessible from home. Recommended.

Thanks Brian for sharing your experience!

From the first phone call to picking up my vehicle, I could not fault anything. All the staff were polite and happy to answer any questions, communication was great as was the work carried out.

Great customer service. They don’t change parts without checking with the customer. Easy online booking system.

The service at G-Force Auto Mechanic was excellent. My car was ready promptly and the friendly owner thoroughly explained a mechanical issue that I had been reluctant to fix due to cost. His solution was much more on point, and way more affordable than 2 previous mechanics I had been to. No question was too 'silly' and he made me feel like a valued customer. I will be definitely be back!

The best mechanic in Australia by far. Highly recommend.
