Rented a car in Munich, Germany from Buchbinder Car Rental through CarRentals.com. in September. Thought I had gotten a good price, until I tried to pick up the car, and found out that I could not decline the liability insurance (which was a whopping $272.) unless I had a Gold MasterCard. No other credit card was acceptable. I had a Gold American Express and a Gold Visa, but they wouldn't accept them. So I had to pay for liability insurance that cost more than the car rental, even though I didn't need any because my AMEX covers liability. I recommend you never book a car with Buchbinder or CarRentals.com unless you are prepared to be overcharged.
