North Eastern Motor Trimmers up holden hill way did a real good job on a mate's 240Z. There is Carafano in Norwood who is renown for his street machine work, but be prepared for it to take ages as it did on my ski boat and another mates car. Carafano's brother runs Claudes Trim Shop at magill which is another option or Aaron O'Hara out at Gawler has a good rep too.
