We just purchased a 2002 AT 37 AVH after a lot of shopping. The boat is absoulutly incredible in rough water. We were out in 5-6 foot seas, and the boat always flew flat, landed without a hint of pounding and never made a sound. The thing was like so solid, I could not believe it. The boat had some hours on it too, it was not fresh out of the mold.
The new Cabin on the AT is also excellent.
Hull efficiency is incredible. Mid to high 80's on 500 EFI's. That is hard to beat.
And you can't forget about Pat and Steve. These guy's are incredible.
As far as holding value. Based on what I have seen out there, AT's will have no problem holding their value and would anticipate their value increasing over the next couple of years.
What can I say, they sold me and I bought one.
One word of advice, go for a ride before you buy. It will be enlightening.
