    As it was when Dennis owned the business, David has picked up the ball and continued to run with it. I was pleasantly surprised to see that David could run his team so well that I'm sure Dennis would be proud. The Company has always, … More as I have experienced it, worked on the basis that a satisfied customer was their their goal for Now and the Future.
    As I have been a customer for many years I have always had the job done efficiently on time and on budget. They are an easy going and effective team, and have been great to look after my vehicle. Thanks.

    We took our Toyota Coaster bus to Trueline and feel so grateful to have been looked after by such an authentic team. We’ve had some pretty average experiences with mechanics in the past and have paid through the nose for work that wasn’t … More even done. Dave and his team were nothing short of superhero’s in our books. Honest, genuine and efficient staff who weren’t out to make an extra buck. We were so happy with the service they provided we wish there was a Trueline team in every town.
