Pros: I got added insurance protection, which I rarely get, for a long trip and I also got pre-paid gas. The fuel gauge facilitated returning the car near empty and accurately tracking mileage. I put about 1,000 miles on the car and had no problems.
Cons: Every time I checkout a car with Hertz, I'm told I'll get an email to complete my Hertz Gold Membership, but I never do. I always follow-up with personnel at the counter to inform them I never receive that email to complete their membership process. After several rentals, I'm still not sure if I'm getting benefits under their Gold Membership program or not. I don't rent too frequently, so I consider this a very minor point.
