They specialise in Prestige cars e.g Porsche
Ferrari etc.
I haven't dealt with Scotts' Audi repair shop, but I did have my Honda repaired at their Honda shop years ago. The quality was okay but little things were missing (i.e. rubber stoppers on fuel flap, trim bits).
I've heard good things about an Audi repair shop attached to Bentley of Sydney. They're in Five Dock.
