Chevrolet Blazer Forum : “what's the kelly blue book price on a 1998 chevy blazer with 50,000 miles”

You didn't say how many doors, which transmission, which engine, or which options your Blazer has, monicaavila, and I don't know where you live. But you can visit http://www.kbb.com/ and enter all that information yourself to get a good idea of the trade-in or resale value of your car. Good luck!
