I am thinking about getting a used insight sometime in the near future. I was wondering about any changes that have happend over the years, expecially important ones like battery.
The only variations I know of are body colour, IMA software, air conditioning, radio, and interior cloth. It is essentially unchanged, which is no surprise considering its limited production.
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 :!:
