One concern of mine if I was to order online, I would want the newest model. In other words, I dont want one thats been sitting around for 5 years, and since then, the model has changed a bit. Looking at pictures of canoes, I've noticed there are things the manufacturer changes throughout the years.
A thread about the relative merits and asking prices of used boats in your area has the potential to be educational. Or at least entertainingly biased.
