In addition to Kip's good reply there were changes in the BCM & MCM that were not fully implemented 'til the 03 model year.
Any older Insight that has had the IMA pack replaced by a dealership should also have these newer design parts. And there were a few recalls (not to be consused with a recal(ibrate) (IMA battery reset) ) in the 00 & 01 years.
Since a recall is for the life of the car (initial "fix" only) then they should be of minimal concern. Just make sure they've been / get done :!:
