Perth had quite a lot of 380's a couple of years ago when I bought mine. Probably the downturn in mining. There were as many 380s for sale in perth as the rest of Australia combined almost. Mine had 74000 Km when I got it, but the problem was it had too few Km to have had anything done. So I got the lot done; Timing belt; trans flush; brakes flush, steering flush; just to bring it up to scratch.
I got it trucked over in a shipping container for about $650.
Mine is at the tail end of production and is a GTL, which is basically a LX model. At the end of production mitsi was using up assorted parts, (I presume) so the GTL is a LX with some black bits on the dash and white leather seats. Slightly different interior colour compared the the LX and the GT.
I'm sure you will find a good one.
