My wife and I had rented a car using rentalcars.com. The pickup was at CTA Airport (Sicily). The company we chose was GoldCar. The kind and available (yet helpless) representative could not fix the issue created by rentalcars.com allowing to rent a car despite not having the mandatory prerequisites for a successful rental (International Driving License). Before anyone could checkout on the site, there must be a full-page, blocking overlay where users can't proceed further unless they had fully read and confirmed with more than one checkbox under the message stating "TO RENT THIS CAR YOU MUST HAVE AN EU-ISSUED DRIVING LICENSE. ANYONE LIVING OUTSIDE THE EU MUST HAVE AN INTERNATIONAL DRIVING LICENSE OR YOU WILL NOT BE ABLE TO PICK UP THE CAR! In short: My wife rented the car and is a US citizen. She was never told she MUST HAVE an INTL. Driving License in order to be able to pick up the car at GoldCar therefore we found out at the teller on the day we went to pick up the car!!! In addition the idiotic policies at the broker, made it impossible to use myself as the driver on my wife's rental as they required the renter to have an Intl. driving license... even if the main driver on the rental was a perfectly qualified driver... Absurd! I have an Italian driving license as I am dual citizen (IT-US) hence would fully qualify to pick up and drive the rental! But no! We had to cancel the rental so I could rent the car under my name. Being out of options we tried... Guess what... No cars were available because my wife still "held" the un-rentable car and no other ones where available that day! More absurdity. So the we were basically forced to cancel or there would be no cars for me to rent... but that's not all! We could not know if there was and what would be the difference in price until we could actually make a reservation for that very same car... and obviously we could not do it via the agent at the GoldCar teller or ourselves... the rentalcars.com agentwe had to call in the UK would do it... the additional nonsense of having to call international made costed us an additional 10 Euro. Truly Revolting!) So once canceled we would have to get a new rental policy and... surprise-surprise... instead of passing the existing rental my wife got for 150 Euros few weeks earlier, it would have to be a brand new one at the cost of 800 Euros for the same car that was ALREADY waiting for us to pick it up! Sheer insanity! So in the end... massive loss of time and money even more massive inconvenience! We lost our rental, we lost 50 Euro to pay a cancellation fee that was not caused by us but by rentalcars.com (we didn't want to cancel to begin with!) not to mention the problems that the loss of the reserved car meant. From having to waste money on bus transportation as we wasted a trip from AG to CT and back (since the 2 visiting relatives could have come to AG themselves), to wasting the whole day between bus rides and later car rides as we had to drive back to AG so we could pick up a car that luckily a family member was able to lend us. That also meant to canceling a previously scheduled visit to Syracuse, (due to wasting the entire day riding buses and driving back to Noto) as well as dealing with the issues created by these incompetents and scammers of a broker! Incidentally, sorry businesses in Syracuse, we couldn't come and spend money there thanks to the subject of this review. So we were left without the much needed transportation means, had to cut and re-schedule our tour of Sicilian cities we were going to visit, we had to waste time and get frustrated for the aggravating experience. I really can't recall an experience that was more horrendous and unpleasant than this one with rentalcars.com. Never, never, never again! Stay as far as you can from these disaster-waiting-to-happen of a company! Regrettably we can't rate it in the negative numbers as they truly deserve. Nobody has ever been a more deserving recipient of a minus 5 stars rating than them! Shame on rentalcars.com their disgraceful site, policies and services.
