I'm thinking about getting this 1998 Limited 4x4, it has about 74k on it and they are asking $15,000. What do you guys think?

 

just based on that info, it doesn't sound like a bad deal.
but of course you're gonna want to get it checked it inquire about this history. do a carfax check on it along with taking it to a shop to have it looked over.

 

15K, thats pretty good, but like calrockx said, make sure you have a carfax done, good luck
