What you may not know is that the warranty on the battery in a toyota Hybrid has a 8 year 100,000 Mile warranty, in most instances the original owner will have sold or traded in the car before the battery warranty runs out on it. Honda has a sinalr warranty on their Hybrid Battery. I sell both the Honda and Toyota Hybrids including the Insight, Civic Hybrid, Accord Hybrid, Prius, and Highlander Hybrid. I am very familiar with these cars and regularly drive them. The downfall of these cars is the time it will take you to recoup your investment over a non Hybrid in a small high mileage car. Depending on driving habits and mileage it could take 10+ years before you recoup the $5000.00 of additional investment from fuel economy savings. David W. De Labio
