CarDelMar 

From the earlier reviews (including my own) it is clear that several problems recur with CarDelMar rentals: cars not being available, insurance scams, and a complete absence of customer service outside (short) office hours. The company will not respond to your complaints unless you sue them, using the European Small Claims Procedure, which is straightforward.

I rented a car for a 4-day trip to Faro and paid for the full insurance coverage beforehand (£19), however I was told on arrival by the local staff at International Car that I didn't have the full coverage. So I paid for it...20 euros a day!

When I returned to the UK, I called CardelMar to complain about the fact that I was charged twice for the same service but their answer to me that it was my mistake and that I should have read the voucher -section F- that stated that you have to check with the local staff if you need an insurance...I believe this is what I did by asking him a question, he just lied to me and that's not on. Needless to say that CardelMar is not willing to reimburse me the £19, the lady on the phone was rather unfriendly ('let me say it again for you', 'good luck with your claim'), shocking!

Awful, avoid, three pointers for potential clients....

1. Don't have a fleet, partner with similar mentality rental fleet providers e.g. Green Motion (avoid).

2. Sell worthless 3rd party excess insurance policies, cosmetically similar to regular rental companies( was fooled by it on their website). But when reading small print, customer is not directly protected at all, rather they must claim back damages incurred, with onus to provide accident reports, police reports etc.

3. To top it all, only contactable between 8am to 5pm between Monday to Friday, any issue outside this window is your problem alone.

I used car del mar in far Portugal and they were terrible. The direction they gave to find our car hire firm were wrong so wasting 45 mins of our time lugging luggage aground the airport car park. They then would not accept my wife as sole driver and we were ripped off 25 euro to add her. Their follow up response to my complaint has been if anything worse. Avoid like the plague

Great site until I typed my Flight details because I am arriving the night before and staying overnight at an airport hotel the system will not allow a flight detail to be installed hence I had to input some information more than once until I twigged.
Kind Regards

very slow and then by the end of the booking said car not available.

Flight was diverted due to extreme winds. We tried to call the pick up point on the number Car Del Mar provided but kept getting the message "this number is not accepting incoming calls". We eventually arived at the pick up point significantly later than expected and were subsequently charged 36 euros which seems unfair given the circumstances.

easy to use but not had the use of the car

so far very good till i pick the car up then i will leave more feed back.

booking and rate is pretty good, but not impressed that they will now need to check with a local agency and only confirm if my booking is possible 3 days prior to my arrival??

Having completed my booking with CarDelMar I was very surprised and frankly annoyed to read this on the confirmation "We will check the availability with our car hire partner at that location as soon as possible - latest within 3 days. As soon as the availability of the hire car can be confirmed by the local company, you will receive your booking confirmation by email. If your booking has to be cancelled due to unavailability, then our Customer Service Team will contact you within 3 days. " IN OTHER WORDS, THE BOOKING IS NOT FIRM AND I MAY HAVE TO START AGAIN. I WILL NOT BE USING CarDelMar AGAIN.

Excellent filters and options; competitive prices; free cancellation and insurance options-- great site.

Appalling customer service. We would strongly recommend not using this company. We turned up to the local car hire company on a Saturday morning and hadn't been told of an extra 126 euro fee to drop off out of hours, despite specifically booking a 4:30am drop off time. The car hire company wouldn't honor the booking and cardelmar helpfully operated Monday to Friday and so we couldn't even speak to anyone. We contacted them the following Monday and were simply told it's local terms so it's not our problem. We will never use this company again.

Would give 0 if possible. Sure, cardelmar is an ok company when you don't need to claim, but having need to claim they told be BEFORE I told them how much I was claiming and what I was claiming that "you'll unlikely get the refund because we rarely refund our claims". As soon as the woman on the phone said this I knew it was a pointless cause, despite it I still tried, and did not succeed. Terrible customer service as the woman also said to me multiple times to any problem or question I had "it's not my problem"

Booking quite difficult, I couldn't get to the summary and final booking without registering an account.

Love CarDelMar. Great prices, great service!

Site was very "flaky". Navigation of the booking procedure very poor.
Example when trying to enter credit card details the boxes were obscured by boxes for different information. Entered details but trying to move to the next step took me back to the same page where card details were blanked out. Re-entered details but moving to the next step took a long time.
During this input process there were links to explanatory terms which indicated they could be printed. A useful guide if it worked but three different explanatory links printed the same coloured burnt out car and useless text, quoting"404 Error - Page not found"
By now I was very close to abandoning the whole process but persevered.
I eventually completed the booking AND payment but was only THEN advised as follows:
"We will check the availability with our car hire partner at that location as soon as possible - latest within 3 days. As soon as the availability of the hire car can be confirmed by the local company, you will receive your booking confirmation by email. If your booking has to be cancelled due to unavailability, then our Customer Service Team will contact you within 3 days"
Not exactly comforting when you think you may not get what you booked after spending a fair amount of time deciding on your choice. There may not be a problem as I have booked well in advance but it could be a problem if booking later. I shall now have to await the outcome.

In this day and age to be told after booking that you need to wait for Cardelmar to confirm the booking is unacceptable
