About five years ago, a friend purchased this item new when they bought a Ferrari, and they said they bought it for around 40,000 yen. It has never been used, and the clear film on the back is still attached, but there is no box. I checked the market price on a used site and found it to be between 7,500 and 10,000 yen. I've reduced the price by about 1,000 yen due to the dead battery, which would cost about 1,000 yen to replace. Please replace the battery and use it. I believe there are no performance issues.
