On the flipside, the rental process is always annoying to me. Even if you find a place that picks you up (so you don't have to actually find one and drive to it), you've got paperwork, you've got mileage concerns etc. It's not your own vehicle, so you're not 100% familiar with it. You have to worry about a return schedule etc -- I don't know about you, but if I go on a trip where I drive a long distance, I typically get home, and go pass out. I don't even unpack the car right away, let alone run to the rental place and return it.
I guess I'm spoiled, then. There's a rental place about 3 minutes from my house. They pick up. They're not super-busy so the paperwork takes a couple of minutes. They have unlimited miles. I schedule the return for the day after I get back, so there's no rush.
The only annoying thing is when you get an Impala...
