Buying a Boat In Europe Need Advice

[SailorFox]

I am considering purchasing a sailboat in Europe but am a little uneasy about the process. I would appreciate any advice from those who have done this. I have seen several boats on the web (YachtWorld) that I am interested in. Not sure whether I should contact the dealers directly and work out a deal or secure a dealer in the U.S. to act as my agent. Also somewhat nervous about the reputability of certain dealers in some countries (Turkey, Lebanon, Croatia). For example I have seen the same boat listed in some cases by more than on dealer. Not trying to be ugly but cautious particularly when dealing with several hundreds of thousands of dollars. Any advice is welcome. Also this is my first post so hi to you all!
