Okay, I want to buy a 1998 SC400. After some research, Edmunds priced it at $10k, kbb and Nada are similar at $13k. this for a 91,000 miles car. So I'm not sure how to proceed, there's a local seller currently listing at $14k. I'm in no hurry to buy one, so I'm just wondering which one I should believe. Any suggestions? Thanks.
