Although I can't speak to buying a boat online, there are two Hobie dealers within a couple hours drive of me. The closest one being about 15 minutes from my house. Once I was done doing my research, I went to the local dealer first, (after receiving a price list from the dealer who was further away).
We talked about the boat, and when it came down to price, I just told him honestly, "I want to support you because you are my local dealer, but I also want to make sure that I'm getting the best price. I'm willing to pay a fair price for the boat, but I don't want to be out on the water having a conversation with someone who has an identical boat, only to find out that they paid considerably less."
The dealer was honest with me, they explained how the other dealer who sells them is new to selling these boats, and they will undercut my local dealers price. Apparently that is what was going on for some other people. They were honest about how much they could sell the boat for, and said that the dealer up the highway would likely sell the boat for $50.00 less. With all the help that they had given me, we decided to buy locally instead.
We are SO glad that we did. I had done some research on roof racks before buying the boat. Until I visited the local dealer, I wasn't aware that they also had roof racks. (They are primarily a sailboat store) The dealer took the time to explain the benefits of all of the different roof racks, and offered us, BY FAR, the best price on the roof racks. When it came time to pick up the boat, they were able to offer us an even better price on the roof racks. They then had one of their people explain exactly how to set up the racks, exactly how to work the kayak, and took more then the expected time to make sure we were completely happy.
We ended up with a defective paddle that the dealer went out of their way to have replaced free of charge, (thanks also in part to Hobie's tremendous quality assurance).
So keep in mind, the internet might have a great deal, but if you have a local dealer, I have to agree with RoadRunner on this one. At least give them a shot to earn your business.
I guess my dealer deserves a mention, as they've been fantastic.
