I buy storage units from time to time, and this Launch X-431 Truck Add-on Module Kit was found in one of them. It's a storage find, but it appears to be in great condition and lights up when plugged into the wall.
I’m not a mechanic and don’t have any experience using this equipment, so my knowledge is limited to a google search. That said, this could be a great deal for a professional mechanic or shop. I'm asking $500obo.
