Performance 4x4
We have worked with the team at Donnelly Engineering for several years now. Over the years we are consistently impressed with the customer service, quality of work provided and turn around times we can count on. When working to time frames and scheduling jobs weeks and months in advance it’s important to be able to trust the companies we surround ourselves with.

Gold Coast Isuzu
I have used Donnelly Engineering for about 10 years now. I was at Hino on the Gold Coast for many years, where I cemented a good relationship with the staff there and when I moved to Isuzu about 4 years ago, I continued that relationship to my new employer. I have full confidence in the Donnelly's team and trust their word for all of my work. We have a great working relationship between the two businesses and Corey is always willing to help and assist where he can. I will continue to use Donnelly's for many more years to come.
