The rentalcars.com company is a web based company from Manchester. However, the company from which I got the car in Bologna, Italy, Goldcar, might be based somewhere else. The complaint was that the actual price of the rental doubled at the counter when picking up the car in Bologna, and the explanation was so vague that the scam did not actual hit until returning home looking at the bill of the rental. I tried to get in touch with rentalcars.com but obviously they did not respond with a complaint procedure in place. They got the money and ran. Stay away from either of these companies: rentalcars.com and goldcar. You will be fleeced.
