Are the DeLorean and the Castle also options? If so, I choose those.
If not, motorcycle and spices. The spices will get me some good money to live off of, and the motorcycle can be stripped to make a rudimentary electricity generator. What I would use it for, idk, but I'd have it.
Wind or water wheel most likely, just need some kind of turbine. I'd probably toy around with ethanol based fuels to try and keep the ICE going, but I certainly wouldn't count on it
