Description: IMA battery completely deleted, gasoline only. Current weight is right around 1800lbs.

Bought with 254K miles for $1500. Mechanically perfect. 99% rust free for being a Michigan car. 1 owner except for the guy I bought it from owned it for 1 week and didn't like it. Has none of the common issues with Insights - no oil leak, no transmission grind, no wet seatbelt issue, almost no rust, rear hatch works, power locks and windows work. Body needed a little bit of work - a little bit of the paint in some areas was scuffed and needed retouching (mostly fixed). Driver's mirror was bondoed on (since removed). Front pumper is pitted and I am hoping to repaint or replace it eventually (partially touched up).

Future Mod Ideas
  • 12V Battery & Charging Mod:
    • Two 20ah deep cycle batteries in parallel
    • Kill switch to manually control Meanwell PSU operation
    • Solar trickle charger for batteries
    Idea is to use one battery for alternator-less driving while charging the other one via solar. Meanwell PSU would operate as necessary to keep batteries charged during higher operation demands.
  • Insight space saver rims powdercoated and mounted on my next set of RE92s.
