Yes, it is a legitimate company -- Car Rental 8 is an online booking engine with service in
125 countries serving 17,000 locations. They are not an auto rental company themselves, rather they are what is called a car rental broker. This means that they have rental car supply agreements with major car rental companies worldwide and their website (carrental8.com) states that this gives them the "ability to negotiate discount prices through booking volumes, which we pass on to you."
When you book a car with Car Rental 8, you are required to prepay the rental in advance.
Renters are issued a voucher for the rental which you must present at the rental counter, along with your drivers license and the credit card that you used for prepayment.
As with any car rental broker, you will not know which car rental company you will be renting with until you recieve the voucher.
Car Rental 8 provides a rate guarantee. Their website states that if you compare thier rates and discover a better rate somewhere else, they can meet and beat competitor pricing for the same car at the same place at the same time. You may call or email them for a price match on a booking.
You can find more information on their website.
