For auctions check out AutoGroup I saw quite a few good cars here when I went a few weeks back. be sure to check out the pictures because sometimes they label the cars wrong and they put down XR6T's as N/A models and vice-versa.GovernmentAuctions is another good one. My advice is not to bother with the Fowlers grp auctions in Moorebank. I dont know what they do but every single XR6/XR6T/XR8 that I looked at had terrible buff swirls all over the car. CarSales is probably your best bet, heaps of cheap cars in here. Go for the private sale, There is quite a few people trying to sell them, some have been in there for well over a 2 months. I ended up getting mine last week for 30k, patience is the key Have fun and good Luck.
