another sad day

I gave my brother the first car I ever bought on my own (actually, the first thing I ever bought on my own period with no help...) my 1994 Plymouth Neon - and we received the worst possible news concerning it. Its dying, its head gasket is about to blow and it needs a completely new exhaust system from the engine out, including the catalytic converter. Total, that's about 2-grand, and thats a lot of money. So, I may have to actually part with it - is going to be hard, but, what can you do....
