If the car:

1. Is available.

2. If the car rental company doesn't pull shenanigans such as cancelling your rental at the last moment due to <reasons>.

3. Is the kind of model you want or need.

4. Has the extras you like/need (adaptive cruise control, etc).

Etc.

In my experience car rentals suck, I wouldn't want to use them except for when I'm flying somewhere.

Lived that when I blew my Class B RV's transmission in Crescent City, CA on the 101 (Van life! Van life! #PortlandiaReference). I was going to be stuck there for a month waiting for parts until I galaxy brained my way out of it by getting my car towed to a dealer in Medford, OR and bought an EV there for below cost the same day, the first EV the dealer had ever sold hence the discount.
