I have written several times before about Autoslash, the service that tracks your rental car reservations and lets you know if they find a cheaper rate.

Booking Car Rentals for our Hawaii trip

If you’ve never used Autoslash before, the basic idea is that you book whatever car rental you want, and then submit it to Autoslash to track. They will periodically check your reservation, using an array of discount codes, and let you know if they find a cheaper rate.

For our Hawaii trip, we were actually going to be on two separate islands, so I made 2 different reservations, and submitted them both to Autoslash

  • Kahului / Maui for 7 days
  • Honolulu / Oahu for 4 days

I made both reservations about 2.5 months before the reservation dates.

Choosing Turo vs. Rental Car

Since the car rental reservations were refundable and cancellable, I actually made Turo reservations as well. The Turo reservations were also cancelable for no charge, and so it made sense to hedge our bets there. We have used Turo before, especially when we travel with all 8 of us (since otherwise we can’t count on having a minivan and have to rent two cars)

For this trip, one of my sons wasn’t joining us, which meant that we could rent a minivan to fit the 7 of us with no problem.

Autoslash Saves Me $483.98

The Turo started out being quite a bit cheaper

  • Kahului / Maui for 7 days – $771.59 for a Hertz minivan, $499.01 for Turo
  • Honolulu / Oahu for 4 days – $421.54 for a Hertz minivan, $303.03 for Turo

But every couple of days, I would get an email from Autoslash

By the time our trip was here, we were down to

  • Kahului / Maui for 7 days – $434.15
  • Honolulu / Oahu for 4 days – $275.00

Adding up the savings, Autoslash shaved $483.98 off the combined prices of our two rental car reservations. Not too shabby for a free tool!

The Bottom Line

If you’re looking at renting a car, you absolutely must use Autoslash. Just reserve a car using whatever program you want, and then put the information into Autoslash’s tracking program. Then it’s just a matter of waiting for the tracking emails, updating your reservations and spending the money it saves you.
