I'm considering buying an older, high-mileage Insight as a second car to compliment my '05 Escape Hybrid AWD, for long trips when AWD is not needed. No specific car in mind yet, just looking around. The original warranty takes care of the batteries to 150k miles, but what potential problems and expenses lurk after that point? Anyone have any experience with maintenance issues on a high-mileage Insight, or tips on what to look for in such a car? Thanks!
