re: Thinking about buying a boat. Questions to ask?

I have driven boats before but I have no experience buying one. And don't worry I won't be taking it down the diversion anyway.

I am looking at buying something like a Tahoe for skiing/cruising. For those that say don't do it, is it just because they tend to drain your bank account? My parents have a camp so I think I'd use it alot in the summer.
