It's going to sell whatever someone is willing to pay for it but...
... maybe more images of WHY the price is higher than what your average RC tanker is used to. I mean, the description does elude to the fact that there is something different in the drivetrain but maybe it can show more proof what went into it.
I think, that if I had the money and wanted it bad enough I would get more pictures before I made the purchase because it IS one of a kind and extremely nice!
Just my opinion!
