Jergofish, I just recently bought a brand new 215cc. Here's the steps I followed. Hopefully, you can follow a similar process and save yourself several thousand $$.
First of all, determine what size boat, options and motor you want. I started out looking at the 195cc, but ended up w/the 215cc after "kicking the tires" at the local dealer. I realized the extra cost was worth it based upon how I plan to use the boat. Then I determined a fair market value for my current boat. Next, I asked the members of this forum for dealer recommendations (see old post - "Dealer Recommendation"). Then I started making phone calls and sending emails. I found the cheapest boats down South (as much as 30% of MSRP). I also had several offers to buy an '05 model at a great price, especially with the re-designed '06 models out in the market. However, I liked the features of the '06 model and decided it was worth the extra cost.
With this knowledge, I started "working over" three local dealers. I sent their emails regarding price and trade-in value for my boat back and forth amongst them. They each moved off their orignal price quite quickly. The process reminded me of buying a new car, but I did it over the internet so it was relativley painless. Then I visited the dealer I felt most comfortable with and sigined a contract. The dealer is installing my GPS system as part of the deal, and I ended up going to the boat show w/complimentary tickets. I pick up my new boat in about one month.
I totally agree w/Cincinnati. An educated consumer is the dealers worst nightmare. Do your homework. Then spend the money you save outfitting your new boat. Good luck!!
