Benetti Sail Division ...rumours?

I am considering a 2005 26m motoryacht by Benetti Sail Division however every time I mention 'Benetti Sail Division' everyone in the industry either shakes their heads, rolls their eye's or starts to mumble. What is the issue? Bad quality build? Bad design? Bad .....?
I get a similar reaction to Bugari (very similar boat), an alternative I am considering ...same reaction!

Anyone have any clues as to what might plague either or both of these builders?
