I have a 96 280 with twin 5.7 carb motors, and here in denver it runs great with 24p b-3s.
You can definetely get a better deal on an older one......... The main change other than the motors, was the interior patterns went more modern on the 2001. I have not had 6.2's yet but the 5.7s in this boat are pretty good moderate performance. You can fairly easily hit 60 with the right props on 300 hp.
Good luck on your search.
