I have rented cars many times from practically every car rental company there is. Some agents are pretty low key, while some can be very hard sell. Be sure to ask your own car insurance agent if your car insurance will cover an accident in a rental car. (It probably will, but it's good to make sure before the first time you rent.) If so, you can turn down the extra coverage they offer you that is so pricey.
Also, be ready when they ask if you want to fill the gas tank yourself before returning the car or have them do it. It may sound like a nice convenience to have them do it, but it is more cost efficient to do it yourself.
Some may also try to talk you into a higher grade of car, for extra cost of course. Be ready to say "no thank you" and stick with what you have. Those extra fees really add up!
If you're traveling with another person who drives, decide ahead of time whether only one of you will drive or whether you'll pay the extra fee for having more than one driver.
If you have a frequent flyer miles no. with any airline, don't forget to find out if it is a partner with your car rental company. If so, be sure to give your FF number when you sign the paperwork so they get it into the computer. If you forget, it can be way more hassle to give it when you return the car (depending on which car rental company and how they process returns).
The only company that I will not do business with again is
Alamo. I had two nightmarish experiences with them, and finally decided enough is enough. However, I know that others have said that they've used Alamo for years with no problems.
Those are some hints that come to mind offhand. Hope it helps a little. Good luck!
