My car has been very good to me the last few years. Shes got 125,000 or so miles. Everything seems to be falling apart. Doesn't want to start half the time. (new plugs, coil, cap, rotor, starter). A/C stopped working completley. I replaced the cycle switch still won't kick over. and the engine is starting to sound rough. wtf. Is it worth fixing or should I just sell it?
