1996 Civic Hatchback repair needs

That I would say would vary. For instance, base it upon what has been done half way recently to the car. Have the belts been replaced, the water pump, the hoses, tires, exhaust. If they are all new you could get by for a minimal cost. I would always figure that the car could cost an extra $100 per month for repairs. Good month, no cost, bank it. There are just too many things to go wrong on an older car. CV joints new? Etc. Ask questions about what was done to the car and how long ago. If the work was done by the honda dealership, you can get a printout of the work performed.
