Had my cambelt and waterpump done last week at Marks Automotive in Prebbleton. Good service, very happy with his work. Cost came in around $750, including replacing Power Steering and Alternator Belts. Genuine Toyota parts, cooling system refilled with Toyota antifreeze and bled. Same day service. He emailed me a detailed quote about 2 hours after I first went to see him, and cost was bang on. Mark was the only workshop I went to that went to the troble of actually pricing for a written quote, and made the effort to contact several suppliers for parts. I would recommend him to anyone that needs a cambelt service.
