I bought a 2006 in 2014 for the same money (with trailer). ZO conversion was already done. Put 500 more hours, and put new engine for 6K and still came out even when I sold it. I think in 07 you don't have to change the ECM to convert to ZO. Savings there. Also, that boat has the analog guage system, as opposed to gateway, which is great. Pics look pretty good. Taken care of, an engine can give you plenty more hours, I think somebody on here got 4K hrs. Just do your due diligence as suggested here by others.
