I can't help too much, Garry, but this info may be relevant. I bought a 2007 Honda megapro in palembang, Sumatra, for $620, and just sold it five weeks later for $470, quick sale. It came with full registration and papers, but because I sold it so far from where I bought it it was devalued as the new owner must change the registration province.
I found it on olx.co.id (just like gumtree) and was helped by a local. If you want local help, try couchsurfing, most people are very happy to lend a hand.
