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.
Some of the Hertz used vehicles I've seen for sale on Hertz car sale lots are pictured with 2 keys/fobs. If you went the rent-2-buy route with Hertz, I'd imagine it would only have one key like your standard rental car would. Regardless, that's pretty crappy they don't at least make provisions for you to get a free 2nd one. That would be a no deal for me given the cost of some FOBs these days, like on push button start vehicles.
Either way, aside from possibly the title thing, none of the above applied with my recent Enterprise car sales experience. 2 fobs came with my truck. They accepted my credit card deposit and would have taken cash or check. They completed the deal w/out even receiving the check yet from my rinky-dink little credit union. I was in my sale's person's cubicle while their finance person spoke directly to the loan officer from my credit union. That was good enough for them which surprised me. My credit union isn't setup to "wire" anything. Due to the COVID situation, they have no office hours and everything is done by US mail or email if you're a member.
In terms of the title, I don't expect to get one with my credit union lien on it for a while.
No theft system was installed.
