New...but not really, Hybrid buyer

Great forum by the way.

I previously owned a Toyota Hybrid (2005) and had fantastic luck with the car. Great vehicle and average a tic over 50mpg with no aerodynamic modifications and merely good tire pressure and the occasional pulse and glide.

I currently own and operate a construction company and want to get my sales manager and operations people (those that don't need a truck) into more efficient vehicles.

I also know how my people treat vehicles and I would prefer to go with a used equivalent so that I don't take the initial depreciation and thrashing from the employees.

Here are my questions:
- Are the Toyota batteries as repairable as Honda batteries (I read the thread about balancing the batteries)
- Is there a general idea about the durability of the two comparable vehicles (Honda and Toyota)?
-- I have owned the Prius and my Dad has the Honda Civic. I must say that I like the Prius operation a bit better.
- Does anybody have the source on the batteries for the cell replacements?


General opinion on the comparison and I am completely open to recommendations.

Thanks and I am open to any and all feedback/suggestions.
