Julie and Jason were absolutely phenomenal to work with, from initial contact and requesting quote to having the work completed. I can’t fault them at all, they are beyond patient and a pleasure to deal with. I sent my ute in for a much needed GVM upgrade. Had a lot of folks trying sway me to not do it because “it’ll drive rougher” “you’ll hate it” “it’ll be the worst money you can spend on your car” well….i wanted to run legal and have suspension that could handle the weight that was already sitting 400-500kgs over. I’m glad I didn’t listen, my ute drives and handles like a dream now, so much better and I haven’t even put all the added weight back on yet. Maybe those complaining just didn’t have the right folks on the job, I’m glad I had the right folks on the job. They even found issues I didn’t even know about from previous owner and fixed those up without a second thought. I look forward to working with Julie and Jason again in the future when I find the next big project for the ute! Much appreciated guys, keep up the great work!

Straight info from start to finish. Jason and Julie were great to deal with and a pleasant change from some of the characters in this industry. Had a GVM upgrade and Dwiz instal done on my 79 and even with a last minute brake issue, job was done on time and done well. Happy to recommend them to anybody. Thanks guys.. 👍

I had a Brown Davis tank installed by another installer in in Brookvale and have always had a bit of Diesel on the tank just could never quite identify it . On a recent trip on the Canning we had a crack in the tank due to the bad original install. Jasons attention to detail not only fixing the issue on the tank but ensuring it was properly fixed showed a second install issue and the root cause of the initial leak . I can't recomend Jason , Julie and the team highly enough for the attenton to detail that is shown in this shop . He has a new customer coming already thanks to the great experience i had . thanks again .

I had a Brown Davis long range tank installed buy their chosen fitter in Perth WA. The tank had leaked when full since being installed. I took the tank back to the supplier who installed it in Perth WA. He was unable to rectify the issue, and the tank continued to leak when filled to the top. To Brown Davis’s credit they still honour the install warranty and sent me to GreenTrees to have it looked at, as I no longer live in Perth. The team at GreenTrees did an excellent job in reinstalling the L/R tank and fixing the leaking fuel issues that the previous installed couldn’t fix. Great job, really happy with their work and attention to detail.

Hi Jason and Julie. I just want to take this opportunity to thank you and your team for all the work you have done on my Landcruiser in such a timely manner. I have just returned from a 3 week trip to central Australia which included crossing the Simpson Desert. The car ran perfectly without any issues. Thanks again.
