When would most of you make the decision to go with a newer boat vs used. So just for example would you buy a 2014-2015 nitro over say a used 2003-2005 ranger 520vx?? What makes you decide between the quality given that both have the original motors. Is it worth having the newer motor on the nitro vs the quality and known ride of the say the 520 from those years ?? Iv seen these two boats about 2-3k dollars in difference and just curious what most of you thought on it.
