No offense, but i think in my opinion if you want a very good job, go to a place that deals with prestige cars.
Charlie Battisti in Nunawading is one of them. Recommended repairer for Porsches, VWs, BMWs, Mercs
Correct Accident in North Melbourne does jobs for Melbourne city Lexus. I have a friend with an IS250 who went there, had his panels resprayed..you can't tell the difference at all.
