Has it been in the bottom of a lake recently? (sorry, different thread we've been enjoying).
Good condition 97 and 98's seem to be in the range of $4,500-10,000. Higher end of the scale usually means they've added some stuff and want their money back (hah!).
Lower end means higher miles, smaller engine.
A Sahara model with 97k? I'd say 6k is a good price.
Have fun with your new ride (this one or whatever you find), and send pictures!
