Autoslash Review: How to Maximize Savings on Car Rentals with Price Tracking and Coupons
With over 20 years of global car rental experience—from my first rental in Spain to recent trips in Costa Rica—I've driven more than 40 vehicles. I rarely join loyalty programs due to infrequent rentals and always seek the cheapest, most compact options for easy parking. I've never booked directly with rental agencies, instead relying on comparison sites like Expedia, Priceline, or Skyscanner.
On my latest trip, I tested Autoslash, a car rental aggregator I'd heard about but never used. Unlike standard comparison sites, Autoslash offers unique features for deeper savings.
What Sets Autoslash Apart?
Autoslash not only compares rates across rental companies but also scans the web for temporary discount codes and coupons, applying them automatically. Results are emailed shortly after your request, ensuring the best possible deals.
It also factors in discounts from rewards programs, including frequent flyer miles, credit cards, rental loyalty programs, and association memberships.
Price Tracking Feature
Autoslash's standout rental tracking monitors prices daily post-booking. If a lower rate appears—often thanks to fresh coupons—you receive an email alert to rebook and save. This feature is exclusive to Autoslash.
You can track existing reservations by entering your confirmation number and rental company—no need to book through Autoslash initially.
How Autoslash Works
Enter your rental details and add relevant memberships or credit cards for applicable discounts. Quotes arrive via email within 15 minutes. For Costa Rica, initial rates started at $10; similar low base rates appeared for Mexico ($0), but always review insurance and fees, which vary by country.
Book promptly to secure deals, as coupons expire quickly. Then, add your confirmation to the tracker—savings are common. While Autoslash once handled rebookings, you now do it yourself, but the time investment yields significant returns.
Discount Coupons
Even for direct bookings, check Autoslash's coupon page for dozens of active codes listed alphabetically by company—a feature absent from other sites. Search by location, dates, and preferred companies to exclude past poor performers.
Autoslash vs. Direct Booking: Real Test Results
Autoslash is now essential for me—skipping it feels like overpaying. The extra steps for memberships and coupons pay off.
For an upcoming trip, Autoslash found superior rates, including via Priceline. Direct checks on the top three providers showed higher prices:
Avis was $60 more; Hertz slightly higher. Savings scale with longer rentals.
Key Tips for Using Autoslash
Only select memberships and cards you possess and carry—agencies may verify. Avoid disappointment from unapplied discounts.
