Texas good, SFO not's so much
Pros: The Texas group were great. Pretty good experience on that end. The car worked well, very reliable. Check out was quick. Somehow, (though I booked online for 4/28 - 5/2), when I arrived at the Texas office, there was a mixup on the dates and rate. They honored the quoted rate. Also, I was told that the reservation was until 5/3 - how that changed I have no idea; my printed reservation showed to 5/; not a problem since they said I could return it "early".
Cons: When I checked in at the Hertz office at SFO, the receipt I received was significantly different from that which I received (prepaid) from the Texas office. I talked to a supervisor in Customer Service; she said she could only give me credit on a future rental as "goodwill gesture". I asked if she could speak to her Manager. The manager authorized the full refund to the originally quoted price. They were kind enough to credit me a partial refund on the prepaid tank refill since I had filled up just before dropping off the car. As a helpful suggestion, I think there needs to a process audit from website purchase to the pickup/drop-off locations and across state lines. It should be a consistent experience - much like a purchase of an airline ticket. Also, there needs to be something in writing at the time of drop off, indicating there was no damage to the vehicle. I asked for this but the Customer Service rep. tried to assure me verbally and finally showed me her screen - the damage box was checked with a "N". That's the best I could get.
