The Gumtree ad does not show the LMCT no. (or QLD equivalent). I don't think it is the main dealership 'phone no. listed, probably just a workshop no. for Dan or Brian.
The other listed items are not 'normal dealership' sale items. Me thinks Dan and Brian are using their work no. and selling stuff privately. The ST1300 may not be sold with dealership warranty or RWC.
Still, a pretty good buy at the quoted km and price.
