Hey mate not sure about the market over here but over east has been
a buyers market with people dropping their prices to unbelievable low
amounts!
Should check out REXNET there is always something going there.
05's with 30,000kms are going for around $33-35k and 06's are going for
around $35-37k with the same low kms.
Carsales and carpoint prices are still quite high at mid $40k
Im also thinling about getting an 06/07 but need to get rid of my 07 wrx
first for a decent price which in todays market is going to be hard!
Hope this has helped
