How much would it cost to get a paint touch up/repair on an older car?

Car in question is a 98 Nissan 200sx, and after discovering I had a decent chunk of change left over in the budget after I got the stuff that needed to be done.The guy/gal who owned it before did a fucktastic job of painting the car, so I would need to fill a hole, correct some running (can't really describe it, but it looks like the paint has runs in it) and just general wear and tear fixing. I'll get some pictures uploaded tomorrow, so you guys can get a better sense of the issues.P.S. I just learned that my car also needs it's 02 sensors replaced, any idea how much that might run me? via /r/cars http://ift.tt/2tXr1LQ
