Apparently, this is still mostly done via paper records. I believe either electronic or paper records are easy to forge. However, that gets into "technically possible, but unlikely". After all, what you are suggesting is that the Hertz (or other large rental) company, to save a marginal amount of money, will commit widespread fraud and risk the massive lawsuit from faking records and then using those records to convince people to buy cars? Meanwhile, they risk damage to a car keeping them from renting it out while it's repaired. And the cost of standard maintenance is probably less than they make in the day or two it's out of service.
