I sold my R1200GS last April (2011) on Ebay. The buyer went with uship. Apparently this is a clearing house where independent shippers bid on posted requests for hauling motorcycles & misc?? The shippers may or may not be bonded or insured, their "haulers" may or may not be up to the task, and the individuals doing the shipping may or may not be very reliable.
The shipper that picked up my Beemer broke down about 25 miles from my house & was unable to deliver the motorcycle. Fortunately, I was able to retrieve it & the buyer & I made arrangements for me to take it to a halfway point, where he picked it up & rode the remainder of the way to his home.
So, . . .be aware of some of these supposed "shipping companies", . . .ask questions, verify insurance etc, . . .before you finalize arrangements & put your trust in them!!
