Car Woes

My car needs work. Again. I don't know if all cars are like this, but I feel like I'm always pouring more money into that thing!! I hate it! This time around I need to replace the head gasket. And it's going to cost me a pretty penny. The repairs are about $1000. Not to mention the $700 I just spent on it in October. Good grief!! I feel like I'm hemorrhaging money these days!! Sometimes I wonder if I should just buy a new one. But then I would have much higher car insurance payments, and a monthly car payment. For now I've decided to stick with it and fix it. I guess... Really I'm not sure. What would you do?...
