Car Troubles

My car decided it didn't like me this weekend.  Aleisha and I were on our way up to a spa day when we got stuck in traffic and then my car started making weird noises then really bad noises.  We stopped to check things out and then turned back towards home and my mechanic.  A few minutes away from the mechanic, the check engine light came on.  I had to leave my car there over the weekend and found out yesterday that one of the cam shafts broke through a lifter.  Normally it would cost $200 for a new cam shaft but I learned yesterday that I apparently have a special engine and so my part will cost $1200 and they can't find it anywhere without ordering it and taking a few days.  The mechanic is contemplating replacing the top of my engine as it would probably end up costing the same if not less.  This all just means that I am without my car for while...too bad this didn't happen in the summer when it wouldn't matter as much.  Steven has let me borrow his car the last two days and I have another offer for this week as Steven will start work tomorrow and will probably need his car back.  Because of the cost of repairs for my special engine, I'm planning on selling my car and buying a new one.  Any suggestions?
