Doing it in Thailand (have been for almost 5 years):

rent: 90 euro, car: 65 euro, food/drinks: 300 euro, visa: 10 euro, health insurance: 15 euro, other: 50 euro

Me and my girlfriend life a very comfortable lifestyle and we really don't cut back that much; eating out here is cheap (as long as you stay away from tourist spots) and we take regular short trips around Thailand and other parts of south east asia.
