I looked on-line last month before selling my 2014 Oasis. I sold it last week for $2400. It was well loved and used but in great shape. The actual asking price you will advertise depends on several items: will you deliver, will you ship, are you in an area where kayaking is popular (clubs, dealers, etc.). Next I advertised on ebay, craigslists and local weekly papers. Because I live in an area with hundreds of lakes with marinas, I placed ads on their cork boards For Sale.
Now what should you ask? Need to sell it soon? Then I would advertise at $2800 - 3000. Just want to sell it but still use it while waiting? Then maybe $3200 - 3500. Just my opinion but hey, I sold mine
