How much is my car worth?

I bought green 1993 Ford Escort Wagon LX last February for $1,300, it only had 63,000 miles on it. Since then I got a tune up, a new battery and a new blower motor. I originally got this car because I just had my second baby and I needed something asap because it was the winter time up here in Minnesota. My car now has 128000 miles on it, How much money could I get for this if I wanted to sale it
