There is another place just across the road from Adelaide Wheel and Rim works called Extensive Wheel Services. They are far superior to Adel W & R Works in terms of quality of work and cost, as far as I have heard and seen.
Most crash shops that I know people from go through Extensive Wheel Services as well so I would recomend it.
Call 8352 5777 or vist 307 South Rd Mile End South
When my wheel fell of I went throught Extensives, it cost me a fair bit for the damage, but for repainting dare say less that 100$.
Hope this helps.
