Lacks clear support guidelines apparently and ignores its customers. I've had issues with two car rentals with CarDelMar and have contacted the Customer Support regarding both issues. The issues were the exact same to the dot (I was charged Border Crossing fees even though CarDelMar's description on the site I was booking the car implied there were no fees). Yet, even though the cases were identical, both support claims were answered differently. One agreed that I was to be refunded, the other one declined and told me it was my fault. After asking the support, how the same case could be handled differently I was ignored. Not to mention the long waiting time to get any reply to begin with. Terrible customer service - would not recommend CarDelMar.

Charge more than they offer! Be carefully! They charged 30 Euros more than in the offer and never gave the money back. They promised me to refund the money but still after two month there was no transfer.

Pro Car - Partner car company Iceland Pro Car, the partner car company near Keflavik Airport, Iceland were prompt upon arrival, hassle free at the office (i.e. no hard sell re extras) and no issues with return of car, with 24hr service back to airport - would use them again. CarDelMar - helpful website but, alas, no response to any emails prior to departure - made me nervous in case I needed to contact them for anything.

Excellent rental car broker Cardelmar has an easy website, good prices and excellent customer service. I booked a car with insurance at Cardelmar. The car rental company sent me a bill for damage to a side mirror the day after I returned the car. I contacted Cardelmar customer service, they replied within one day. I sent all the information they needed and they processed my claim within 4 days. Wow! That's what I call good service.

My Car Del Mar Booking, This company provided an excellent service. My wife and I were picked up in the airport car park and driven by minibus a sort distance to the office where we picked up our car. The friendly staff checked my details and after an examination of the car (first time ever with any rental company) we were on our way. Seven days later we return the car, it was examined by staff, and were returned to the airport. Its a no brainer where I will hire a car next time I go to Portugal!
