How much could I get if I sold my car?

I have a 98 Jeep Grand Cherokee Limited, and recently the radiator and water pump started leaking, and I can't drive it. It is a $600 fix, and I can't afford it. So, I am thinking about just selling it as is, and buying a cheap different car with the money, because I need a car to get to work. How much do you think I could get for it?
