Well, if you think it is worth 6K, put it up for 6K. I sold my '93 for $2400, quite a way above book, but when I talked to people about it I sincerely believed it was worth that (and still do) as I had taken good care of it and had a fair amount of work done on it. Might as well try to sell it higher than lower. Hopefully you aren't in a rush though. The more time you have to sell it the better situation you'll be since you can turn people down who offer less than you are asking.
