This seller has sold two others for a buy it now price of $800. The Lightning chassis is was produced in smaller numbers than the nitro UE thunder chassis. I'm not sure I'd call it rare, but I paid more than that for the one I bought a few months ago. Mine was in flawless shape (was a show truck) and came with Emaxx 2 spd trans, UE TI center dogbones, servos and the rx.

Its nice to see them go for that much since its telling me I didn't overpay for mine. If you want one, gotta be in the right place at the right time and pay the going price.
