Rental Car Hacks – The Car Rental Tips & Tricks you Need to Know

Rental cars are often a key part of any trip (business or pleasure). And, if you are business traveler, it’s likely you are spending a significant amount of time in a rental car. If you are leisure traveler, it’s likely that a rental car plays a large role in the success of your trip (ever tried cramming a family of 4 into a small Kia?!?).

Whatever your reason for renting car, it’s likely you want to save money, avoid unnecessary time-wasters and get the nicest car you can with the least amount of hassle.

So, with that in mind, buckle up and settle in. Here are some great 9 Secret Rental Cars Hacks every traveler ought to know (and that the rental car companies don’t want you to know about!).

But first…a funny video about renting a car

Please enjoy this funny video about renting a car…you will thank me.

Rental Car Hack #1: Skip the insurance.

Rental car insurance is pretty much just a scam.

It’s likely your personal car insurance covers the rental or if on corporate travel, your company’s insurance.  It’s not needed, unless you literally have no other insurance options some where else. If that’s the case, you are probably not a business traveler…and more like a 26 year old kid in college. :-).

See this article for ideas on how to rent cars when you are under 25: What’s a young driver fee & what’s the best under 25 Car Rental Company?

It’s also possible that your credit card (yes, your card!) might provide additional coverage for your rental car as well.

So, skip the rental car insurance. You can save some serious money with this rental car hack.

Rental Car Hack #2: Sign up for reward programs.

If you’ve been following all of our travel tips and advice, you’ve been maximizing the value of your travel by signing up for travel rewards programs. Don’t forget to get on board with a rental car company’s program.

They offer lots of benefits that you can use to your advantage (like scoring free rental days, or upgrading to a luxury car, or skipping the normal rental car lines).

Here’s a few of the more popular ones:

Rental Car Tip #3: Pay attention to the the bonus programs the rental companies often offer (and require you to “register for”) – you could be missing out on some extras. 

In  addition to signing up for your chosen rental car company’s rewards program be sure to keep an eye out for special incentive programs. Often rental car companies will offer incentives (e.g. rent 3 days and get a 4th free). But, if you don’t periodically check their website or sign up for alerts you’d miss them.

Rental Car Trick #4: Never prepay gas – it’s likely a waste of money.

This is another scam you can avoid by employing this rental car hack. Using whatever prepaid gas options they have is a dumb move. And it’s stupid expensive.

Rental car companies charge you for a FULL tank even if you only used up 1/4 tank. And it’s at a much higher rate (like double in some case for the “labor” of someone pumping the gas for you).

Plan your return with enough time to fill up before you return the car and save the money.

Note: Many companies actually prohibit employees from taking this option – forcing you to fill it up yourself before returning it. And if you are a leisure traveler, just do it yourself…it’s not that hard!

Rental Car Hack #5: Book early to save money.

Typically, the earlier you reserve your car the better rates you will get.

As the cars on the rental car company’s local lot get reserved, prices start to inch up. Usually you can cancel a rental car without too many repercussions so reserve one earlier even if you don’t have your flight options sorted out. Not only will this lock in your car, but it locks in a better rate.

Rental Car Hack #6: Rent from the rental car company directly to save money.

While business travelers may be prohibited from doing this, book direct and you might be able to get a better rate and/or be able to use a discount code.

Certainly, if you are on vacation, go direct and skip sites like Orbitz and Travelocity (unless there’s some crazy good deal bundle they are offering you).

This is another fun little rental car hack you can use to save money and I have almost always found the rates to be cheaper when I book direct.

Rental Car Hack #7: Download the rental car company mobile app.

Most rental car companies now have a mobile app (some are better than others). Car renters can use these apps to book cars, pick them up, track your rewards progress and more. Some even allow you to call for roadside assistance if need be.

Rental Car Hack #8: Ask for the upgrade.

This is one of those “cherry on top” rental car hacks. You’d be surprised at how often they will give you the upgrade if you just ask.

This is certainly the case if you are a seasoned regular traveler (you may even get the upgrade automatically). But, even as a regular car renter you it doesn’t hurt to ask. Maybe it’s a slow day on the lot, or maybe the attendant is just feeling nice.

Rental Car Hack #9: Book using a group membership discount code.

Often, organizations like AAA or AARP will offer their members discounted rates for various products – including, at times, rental cars. You may be able to save some cash by using these programs.

AARP Rental Car Discounts

Even if you are booking the car on the company’s dime, using your AAA code could save the company a few more dollars. In fact, I once worked for a company that required us to use our AAA memberships to rent cars to save money.

Bonus Rental Car Hacks & Car Rental Tips

Here are a few extra car rental tips to help get even more about of the renting experience.

Bonus Rental Car Tip #1: Get an AC-Mounted Magnetic Cell Phone Holder for your Phone and go hands free!

This is one of those practical car rental hacks, if you will. Your personal car back home probably has a hands free attachment of some sort. It may even be mounted somewhere (permanently, in many cases). But, when away in a different location, how do you stay hands free while trying to find your hotel?

Simple. Use an AC-mounted (removable!) magnetic cell phone holder like the WizGear model depicted below. I highly recommend travelers bring of these babies with ’em on your next trip. You can read my WizGear Product Review here.

Bonus Rental Car Hack #2: Don’t forget to check your car out before you drive it off the lot.

Make sure you do a walk-around and check the car you are renting for any damage. If you find it, take a picture of it, and if you have time, let the staff know so they can add it to you rental car record. No need to pay for something that’s not your fault.

Bonus Rental Car Hack #3: Consider buying a pre-owned rental car for personal use. 

Conventional wisdom says don’t do this because they’ve been rode hard and put away wet.

However, here are the CBoardingGroup, we’ve found the opposite to be true. Rental Cars likely followed regular maintenance schedules, were fixed when damaged, and are usually only 2 years old.

We’ve found some wonderful vehicles this way (we have a 2007 Suburban w/ 170k miles on it now that was a rental). And you can usually get a good deal.

Here’s a few places you can buy rental cars:

    I’m pretty sure #5 is not a good generalization. I usually book early and then re-book as rates go down.

    1. The C Boarding Group Post author

      I’ve seen them go up and down, usually down, but I think it depends on where you are traveling to and what times of year. If you book a rental car in NH for Leave Turning season in the Fall…rates go up the closer your get.

    Not terrible tips however the insurance tip is only good for domestic and maybe Canada rentals. Most personal insurance will only cover rental cars for domestic USA and Canada. International locations are a different animal and may be partially covered by credit card coverage. Also some countries have some levels of insurance that are mandatory.

    How is Autoslash not mentioned? I’ve found they almost always get the best rates. Yes, better than booking direct.

  4. Jonathan

    One site you may not be aware of is autoslash.com. AutoSlash automatically finds the best deals up-front using all the coupons and discounts you qualify for (Costco, AAA, AARP, USAA, etc.). You can also track any rental (even if you didn’t book it with them in the first place) for better deals. Prices are checked daily and you’ll get an email if AutoSlash finds a lower rate. Prices often drop as the pickup date approaches, so this can save a significant amount of money. Best of all, it’s a free service.

    Here are some awesome car rental hacks for your next trip:
    If you are a US citizen you probably have membership like Costco of AAA that you are already paying for, you can use them to get a great deal on a rental car
    Always make sure to check you credit card benefits before buying the insurance
    Do not overpay for gas
    Check the car for damages and take pictures before driving out the lot
    Avoid peak travel times

    Hi! My fiance and I are going to be driving in Italy for our honeymoon later this year. We’ve read stories about rental companies charging you on return for a full tank of gas, even if you returned it with a full tank. Have you guys ever experienced anything like this?
