Be warned : the camera trained on the auctioneer is beamed straight to you .
提醒：对着拍卖人的摄像机将图像直接传送给你。
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 .
