well, i bought mine from sydney, from a sales yard. saw it and fell in love. the used car market was slow when i bought my car, so i did the hard deal on them and got $3000 off the price. not sure what the market is like now, but i dont think that it wouldve improved much.
basically, i think you'd better off looking in sydney, the market is much larger up there and your more likely to get a better deal with so much competition. be careful though, make sure it will pass rego in the ACT.
