Last year, I wrote about the best ways to save money on car rentals.  At the time, 1 of the best tools to use was AutoSlash.  But they stopped working (properly) after a while.

But now, folks report that AutoSlash is back.  AutoSlash will track your car rental reservations for price drops, and re-book you at the lower rate if your rental becomes cheaper.

They’ll watch reservations made with most major car rental agencies.  And if you booked your car through AutoSlash, they’ll monitor your reservation automatically.

AutoSlash Says They’ll Monitor Your Car Rental Reservations and Rebook You If the Price Drops

I decided to experiment again (not like this) to see if AutoSlash could save you money.

How Does It Work?

Link:   AutoSlash

AutoSlash is a free service which tracks your car rental reservations for price drops.  They’ll re-book you at the lower price if they find one!

You can track existing reservations made with major car rental companies, or book your car through AutoSlash (and they’ll monitor the reservation automatically).

AutoSlash Does the Work of Checking Back for Cheaper Rates

I did some searches on AutoSlash to compare their prices.  And I made some dummy bookings with car rental companies for them to track.

What Are Their Rates Like?

You can search for car rentals on AutoSlash and they’ll try to find you the best current, published prices.

You Can Use AutoSlash to Search for Cheap Car Rentals

Some searches give you immediate results.  For example, I searched for a compact car in Seattle next May, and they returned rates from Sixt and Payless rental car agencies.

AutoSlash Returned Results From 2 Car Rental Companies

If you book through AutoSlash, they’ll automatically track your reservation for price drops and will re-book you with the same rental company if it does.

I made a (refundable) booking with Sixt (through AutoSlash).  The total price for the rental was ~$222.

This didn’t strike me as the best possible deal, but we’ll see if Autoslash finds lower rates as the rental date approaches!

Just to compare, I checked the Chase Ultimate Rewards travel portal for Seattle rental cars on the same dates.  The cheapest deal was for $260 with Alamo (also a refundable rate).

Chase Ultimate Rewards Travel Portal Didn’t Find as Cheap a Rate as Autoslash

Note:   If you pay with Chase Ultimate Rewards points, they’re worth 1.25 cents each.  So this could be a better deal for some folks.

I also checked Hotwire.  You don’t find out the name of the rental company until after you book and pay, and the rate is non-refundable.  But they found the same type of car on the same dates for ~$187.

Within an hour of making the Sixt booking with AutoSlash, they sent me an email:

Will AutoSlash Save You Money On Car Rentals
AutoSlash Found a Cheaper Rate Within an Hour of Booking Through Their Site

I responded yes, and they’re re-booking me at the lower rate!

AutoSlash Is Certainly Quick at Replying!

We’ll wait and see if AutoSlash can find anything cheaper!

Note:   Remember to use a credit card that offers primary car rental insurance (CDW), like the Chase Sapphire Preferred or Chase United MileagePlus Explorer.

Even if you book your car through AutoSlash, the purchase is from an actual car rental agency, so you’ll get the credit card insurance coverage.

Tracking Current Reservations

I wanted to see if AutoSlash would truly monitor reservations, find lower rates, and re-book you.  So I made refundable bookings with different rental agencies in various cities, between 2 weeks and 8 months ahead of time.

1.   Washington, DC

I booked a 1-day rental in Washington, DC, with Budget car rental.

A 1-Day Rental in Washington, DC, Costs ~$82

After the reservation was confirmed, I entered the confirmation number and booking details on AutoSlash.  That included my name, email, rental dates, car rental company, reservation number, and total price.

I got a confirmation email shortly afterwards, saying that AutoSlash is now tracking this reservation.  They also offer to search for cheaper rates at other rental companies for you, if you wish.

I booked this reservation ~2 weeks prior to see how AutoSlash performs with short notice!

2.   Austin

I made a week-long booking with Thrifty in Austin.  It’s during a busy travel time, so the rate is expensive.

A Week-Long Booking With Thrifty Over the Holidays Costs ~$332

Again, I submitted the reservation details to AutoSlash.

3.   Kauai

A compact car in Kauai this April, booked with Hertz, costs ~$239 for 5 days.

I submitted this reservation to AutoSlash, too.

4.   Toronto, Canada

I wanted to see if AutoSlash had different luck with reservations in other countries, so I booked a car in Toronto, Canada, next summer for 2 days with Avis.  It costs ~228 Canadian dollars (~$202).

AutoSlash is now tracking this reservation, too.

The Results!

1.   Washington, DC

I got an email from AutoSlash 3 days before my booking.  They found a rate ~$26 lower than my original reservation.

That’s not bad savings for a 1 day rental!

2.   Austin

AutoSlash emailed ~2 weeks prior to my reservation with a lower rate.  First, they saved me ~$167!

They emailed again about a week later, and found an even better discount.

Closer to My Reservation Date, AutoSlash Found an Even Better Deal, Saving Me ~$206

A savings of $~206 is substantial!

Because my last 2 bookings are months away, I’ll write an update post to let you know how much money AutoSlash saved me!

Bottom Line

AutoSlash is a free service which tracks your car rental reservations for price drops, and re-books you if the price goes down.

You can also book rentals directly through AutoSlash, and they’ll track them automatically.

And it actually works!  AutoSlash found significantly lower rates on my 1st 2 reservations, for a total savings of ~$232.

I’ll write an update post when I have information on my last 2 reservations.  So far, I’m definitely impressed!

Sorry folks, we were mentioned on ABC World New Tonight last evening as the best place to get a great deal on a car rental and it almost crashed our site. We added some capacity quickly though so thing are humming along smoothly again. Thanks for your understanding.

Website is working now. http://www.autoslash.com/

I have attempted to pull up the site for Auto Slash, but it does not open. It sent me to their face book page. I wanted to find some info on rental in the NC area I would soon be going to. Oh, well!

AutoSlash does not work – buyer beware. I made a reservation there and found the rates to be about what they were elsewhere. I did a quick check a month later on rates and found rental prices had gone down by almost 50%. Autoslash did not reduce my rate. In fact when I called them to urge them to do what they claim, I was told they had no control over their service. It is all generated by a computer system. The rep says they could do nothing at all – in fact she wouldn’t even look up my reservation to confirm. Asked for a supervisor and was put on permahold indefinitely. This feels scammish to me. Customer service just blames a computer they have no control over. Mistakes can happen, but their lack of action is inexcusable.

Has anyone tried RELAY RIDE car rental share? It is almost like Uber but you rent a personal car near by you for half the price of a regular rental.I think this is how many cars will be rented in the future. I use to be able to rent a car for $20-25 bucks a day but know i am lucky to get a car rental for $40 a day. I think it is a great idea since the company is insured and has road side assistance if something happens.
