I had a total car rebuild in January 2014. Immediately after, the car used excessive oil consumption. I contacted the mechanic prior to 1000km service. At the 1000km service, the 5000km service and 10000km service, he made excuses and then tried to blame me for glazing the bore (which was not warranty). However this was all verbal conversations we had. Good mechanics (after 5 months of dealing with this bloke) did another complete rebuild. They were totally amazed at the disgusting job this guy had done, and said that they have documented and photoed the problems. I am just not sure whether to take this to NT consumer affairs or small claim courts under Australian Consumer Law? The initial works cost $6200.00 (however I have lost his invoice, I can prove payment). I live in the Northern Territory. Just wanted some advice which is the best option. Cheers.
