iv seen some 32's go for 6K, i purchased my last R32 GTST Auto for 6500 from NSW but by the time i freighted it, cleaned it up alot, converted it to manual, put rego on it, it owed me about 9K.....if you purchase one ex east you will pick one up cheap.. auto's are allways cheaper, manuals you pay a bit more for usually. most 32's under 8K are usualyl pretty rough tho..
if your buying a 32 under 10K be prepared to throw some dollars at it for maintanence
