We have had decent luck on craigslist. However, there is a lot of junk that goes on from both sellers and buyers. Just be diligent and eventually the right person will come across your ad.
My ad for the TT we sold included a list of the upgrades and known issues (it was a 95). My description was very detailed about condition etc... The first person who looked at it bought it.
So something you may want to do is have an independent person look at your ad with no skin in the game (trusted relative or friend) and give you an honest report of your ad vs the trailer and see what they say. Is something in the ad giving a false impression? Maybe, maybe not. Also, I have had success with posting my "bottom dollar, non negotiable price".... Funny how many people out there like that... Many folks hate "dealing" and will pay a fixed price if it's fair.
BTW, my dad has an 01 challenger, they are very nice rigs!
Thanks!
