sebastian072013 made a winning bid on this vehicle and won the auction on 4/5/16 but decided to not pay. His words "Sorry i dont want it no more becuas its to far from were i live and habe no car " The location is CLEARLY listed in the description above. A second "winner" won the auction then within 10 minutes of winning cancelled with no word as to why. "EAKWAKU" won the auction as well, the third time it was up after bidding on the vehicle in the first two auctions, then never responded to repeated attempts to contact. PLEASE DO NOT BID IF YOU DO NOT PLAN TO BUY - YOU WILL BE REPORTED AS A NON-PAYER.
