Be warned : the camera trained on the auctioneer is beamed straight to you .
提醒:對著拍賣人的攝像機將圖像直接傳送給你。
Common sense would suggest some information-a car 's age and mileage-is essential , but that total transparency about other things ( precise details on subpar paintwork ) might deter buyers , lowering the auctioneer 's commissions .
