I saw a 2008 Jeep Liberty diesel for sale on craigslist (Phila., PA). There are ways to "jump" the electronics on post 1973 diesels, check Youtube and by all means read James Wesley, Rawles. That would be an exellent G.O.O.D. vehicle. You will be able to use bio-diesel, and for a short time after SHTF, #1 Fuel oil (heating oil), but it will eventually clog your filter and/or injectors.
