I didn't read the previous posts, so forgive me if there's duplication...
I wouldn't buy at a boat show. I'm just not comfortable with impulse buying with that much money. The only exception is if the buyer knows exactly what they want, exactly what they're buying, exactly what a good deal is, and have already taken a sea trial on the same package. The gelcoat looks shiny under the lights, and the salesmen talk a good game, but the boat shows are primarily for comparing boats side-by-side (or almost). The last thing you wanna do is spend tens (or hundreds) of thousands of dollars, then realize a few days or weeks later that there's a boat you like better. If I pay a little more later for the same package that was at the show, so be it... (but many "deals" at the show can be had later regardless of what the salesmen claim). But that's just me...
