Sold or traded? Just curious, if sold then that was a quick sell!
I thought about selling my 04 Concept before trading it in on my 07.
Problem I see with most CC's on the re-sale market is power. CC's are fairly easy to keep new looking even if they are older- new upholstery, good buff/wax, few new gauges and you have a new boat sans power. Nobody wants to drop $X on a used CC knowing it needs $35K worth of new power and the flip side is nobody wants to drop $X because a boat has 60%+ of it's value in new power.
Ended up trading it in- I like boating, not being a salesman. Not that there is any thing wrong with them...
