I've never looked back since I took my car to Peter at Kmart Auto in Annandale (years ago), even after moving to the Northern Beaches.
Peter is an honest no gimmick mechanic whom I know I can rely on.
He's never tried selling me what I don't need and offers competitive prices. Always warns me ahead of time what may need fixing or replacing and my car is always ready at the specified time - on time every time! Highly recommended!
