Not a scam, but seriously not a good idea. When there's a problem with your rental they blame the rental car company and don't back you at all. The rental car company blames car rentals.com and your left holding the bag

So far, it's a scam. I paid them then had to pay again (2x the amount) at the rental pickup.

Scam, don't rent from there. I just got scammed from them for the last time. Their favorite rental car "agency" that they want to promote is the biggest scammers of all "u-save"

Very very poor customer service. My reservation was lost that I'd already been charged for. I was then forced to rent a vehicle at a "walk-in" rate after both companies were blaming each other fir the lost reservation. I was told by this companies representative I'd receive a refund for the difference in price of my original reservation I'd already been charged and the new reservation, $190. This was November 8. I just received an email informing I would not be receiving a refund. Do not use this company!

Carrentals.com is a scam outfit. Never pay in advance. Read the fine print. I have been traveling and renting cars for 40 years and have never dealt with a more unprofessional or dishonest travel company.

Not sure if it is a scam but in the end I felt screwed!
