Such wonderful people to do business with. They did an excellent job of finally finding out what our problem was & fixed it. So glad to finally have our car running smoothly as it should have been a long time ago.

Core Diesel Maintenance recently completed repairs on our truck. They were meticulous, kept us updated every step of the way & nothing was a problem. We can highly recommend them & we will be taking all our trucks to them in the future.

Some of the best service I’ve had in years! The amount of communication and follow-up calls was outstanding and the service provided in the end could not have been better we are Very happy with this company and will be using them for all repairs and servicing.

Took my 4wd to these guys when no one else could diagnose and fix it. Issue was found and fixed that day. These guys were recommended by a friend, couldn’t be happier with the service. Will be using their services again.

Excellent customer service! Kept me updated with very thorough reports including photos. Thorough vehicle inspection highlighting things to do in future. Definitely recommended for peace of mind trouble free services.

Core Diesel have proven to be a very professional and accommodating company during my experience over the past few years. Our fleet of trucks have always been prioritised and professional serviced in a timely manner and they have always offered good advice on keeping our fleet in tip top shape 👍
