Pray for my car!!

So, I'm not sure how much longer my car is going to run. :(
My dad just poured a lot of money into redoing the whole back end. And now the transmission is going out. Well, has been going out for awhile, but getting worse. I was afraid I wouldn't make it home tonight!
Some of you might wonder why I drive a 95 Lincoln Town Car. Its not for looks I can assure you! It was a gift from my dad- a loner car that would be "free" to drive till I left for Thailand. He is planning on selling it when I leave. He drove it all the way out here by himself from South Carolina so that I could save my money and not have to spend it on a car. He bought it at an auction, got a great deal and was going to be able to get what he put in it after I was done with it because it had such low miles and was in such great condition. Well now he's already put into it with repairs, almost what he paid for it- and now this.
I'm confused and praying for wisdom because I don't understand what I'm supposed to do. Do I take the money I have in savings for Thailand and buy a car I'm only going to drive for a few more months? That "logically" doesn't make sense to me. I'm praying for wisdom or a miracle. Please pray with me!
