I got to looking in to the Hertz thing a little more, and I am backing off for now. A couple of things that make it less convenient are:
1. Hertz only provides one key with each car. You do not get two keys like you traditionally do when purchasing at normal retail. Not sure why that is the case, but it kind of bugs me. Where is that 2nd key and why do they not include it?
2. Payment options are either certified cashier's check or wire transfer. No personal checks or bank draft checks are accepted. I get why, but it is quite inconvenient. Normal car dealers take personal checks no problem and seem to be able to make it work.
3. Hertz does not have the title to the vehicles at the store. It can take up to 6 weeks for the title to be sent to you after you take delivery and pay for the car. This is a small detail, but still kind of bothersome.
4. Some vehicles have rental theft recovery equipment mounted in them. Hertz "removes" that prior to delivery. Not sure how invasive the installation of that equipment is, but not sure I like the idea that some sort of tracking equipment will have been installed and removed. Is it spliced in to the electrical system...could it cause further issues down the road if not properly disconnected, etc.? Probably a non-issue, but just makes me wonder.
