The early model boats came with a Volvo engine that they had repetitive failures with. if i remember correctly it was due to heavy oil consumption. that why they discontinued use of that engine. if it still has the Volvo engine i would be VERY hesitant to buy that boat unless its such a great deal you can afford to put the new engine in it.
the composite hull is very impressive, but there are lots of cosmetic imperfections in the surface. That why all the preproduction and early models came with a "wrap". it was to cover up and hide the imperfections.
do your homework, get on wakeworld, talk to early model owners find out the issues they have. the newer boats i hear are better but 07 was the first production year. i personally would find another boat or a much newer model and then i would make sure the problems Ive talked about have been fixed and are holding up.
a local guy here in CAL had one of the first preproduction models and he customized the crap out of it "cosmetically"and then had such bad issues they wanted to replace the hull. he wanted a whole new boat. i don't know what came of it. DO YOUR homework!!!
