It was actually listed at $29,950- previously, but he seems to have upped it $5000-. About two to 3 times the going Oz price depending on just how good it actually is - $18,000 would be absolute top, and excellent bikes change hands for less than $10,000-
There was a decent R80 G/S PD for sale on Oz Ebay a few months back, bid to $16,500 ish but didnt reach reserve, sold a couple of weeks later to one of the early bidders for $10,500- in a non ebay private sale, so dont trust that everything on Ebay is kosher.
