I rented a car through Gold Car at OPO. The car was absolutely filthy but ran OK, the service, well a bit strange. Not friendly and a bit pushy but hey, I got my car and off I went. Had a fabulous three week vacation through Northern Portugal which was just amazing.
Fast forward 10 months. My credit card was charged AGAIN by Gold Car!!! I immediately contacted my credit card company and both myself and my credit card company contacted Gold Car in the USA. Fortunately, I still had the confirmation email from last summer's the rental. The Gold Car rep had no answer as to why I was charged again 10 months later and even asked me for my credit card number! Really? I've had to cancel the card, report the charges as fraud and will now have to wait for a new card.
I thought I'd give the company a chance, and thought I could save a couple of dollars. I didn't save any money using them and now they are trying to rip me off. Never again...stay away! There are far more reputable car hire companies in Portugal
