I had my first experience this week with Hertz' Gold Choice program at CVG. As soon as I turned on my cell upon landing, I received a text message with the car, stall number, and Gold Choice option. My assigned car was a Toyota Carolla, but I opted for a Chevy Cruze from the Gold Choice area. I drove off the lot happy, but then.... When I turned in my car, I noticed a $5/day charge for XM Radio. This wasn't indicated anywhere in/on the car when I selected it and it was among the standard Gold Choice vehicles (not with the vehicles with upgrade fees). I asked the individual who accepted my return and she explained that I was responsible for any premium features included in the car I selected. There was nothing to indicate that this car had XM Radio (short of starting the car and flipping through the radio controls prior to driving off the lot). If I wanted to challenge the charge, I would need to go inside to speak with someone. It was early in the morning and I didn't have my coffee yet, so I decided the aggravation wasn't worth the $10 bucks (2 days at $5 per day). The website says that Gold Choice is FREE unless clearly marked with 'per day' additional charges. So, what gives? From Hertz Website: Do I have to pay for Gold Choice? No. When you reserve an intermediate car or above, you can switch to any comparable vehicle in the Gold Choice area at no extra cost. Specialty cars are available at clearly marked ‘per day’ additional charge in the Gold Choice Upgrade area. We also have dedicated personnel to assist with your rental or answer questions. If you don't see the car you are looking for they can help you find exactly what you are looking for.
