Fleet management tips needed

At my current job, I am facing a bit of a challenge managing our company’s fleet of about 70 cars. I have searched the internet for good fleet management software and I found few good software but I am not sure about the quality of these software.

Does anyone know of a good fleet management software?

Challenges that we are facing with our fleet of cars:

1- Rental history
2- Accident history
3- Maintenance history
4- Mileage
5- Cost of ownership
6- Warranty information
7- Checkout and check records

Of course we have some type of records for our fleet, but I like to have a complete control of our fleet where no part of fleet management is over looked.

Does anyone know of good software for fleet management and also any tips in this subject are welcome
