Hands down the best mechanic in Cairns, have been going there for years. I think they specialise in 4wd vehicles, but Ive seen really old Jeeps, a Transam and a fair number of ritzy cars there in the time Ive been using them. I found that they have lots of experience and knowledge and have always been honest. If there is something that they need to do above the base service, they will always contact before going ahead which is appreciated. Found out about them by a local 4x4 forum in Cairns and gave them a try as they all were quite happy about putting their modified vehicles through there.
