1973 ? I think. From what I've read on forums the 796 serial no.puts it about there. The Imp has been used but not badly abused. It starts right up and runs good when it feels like it, I believe it has carb issues. It comes with 2 sets of tracks, the ones that are on it are 25" wide, the other ones are 31". Comes with a parts manual. The price is $10,000.00 Canadian. Americans interested should check the exchange rate. I am located in North West British Columbia.
