I also go to Harry's. Alloy wheels are usually hard to find though. Sometimes you can find one or 2 but a set of 4 would be difficult. Most of the times the car has been hit and some of the wheels are damaged. The alloy wheels go fast.
I may be there this week end if the weather is nice and I can block off the time. It is an hour and a half to get there for me.
