Renting a car used to make us nervous. The process felt complicated, the costs added up quickly, and we were always worried about missing something in the small print or being charged extra later.
After renting cars in different countries and even on different continents, we’ve become much more confident. We’ve learned where to search, what to check before booking, and how to avoid the fees that can turn a cheap deal into an expensive one.
Our Best Tips for Saving on Car Rental
1. Use a Car Rental Comparison Site
As with anything expensive you book online, using a comparison site can save you a lot of money on car rental.
We wouldn’t recommend choosing one company randomly and booking directly without checking other offers first, because prices for the same dates and destination can vary a lot.
Our favorite site for this is DiscoverCars because it makes the comparison easy and transparent. We especially like that the supplier rating is visible right away, so we can quickly skip companies with poor reviews, even if they show the cheapest price.
For us, the best deal is not always the lowest number on the screen — it is the cheapest option from a reliable company.
2. Compare the Final Price, Not Just the Daily Rate
One of the biggest mistakes you can make when renting a car is choosing the option with the lowest daily price without checking what is actually included.
Some rentals look cheap at first, but once you add taxes, airport fees, insurance, deposits, mileage limits, and required extras, the final price can be very different. We always compare the total cost under the same conditions before booking.
A slightly more expensive offer can sometimes be the better deal if it includes unlimited mileage, fair fuel rules, a lower deposit, or a better-rated supplier.
3. Book Early, but Keep Checking Prices
Car rental prices can change a lot, especially in popular destinations or during high season. We usually prefer booking both car and hotels early with free cancellation option.
This way, we already have a car secured, but we can still check prices again before the trip and rebook if we find a better deal.
DiscoverCars currently offers free cancellation up to 48 hours before pick-up on many bookings, with a full refund of the prepayment if cancelled in time, but always check the exact cancellation terms before confirming.
4. Compare Airport and City Rental Locations
Renting a car at the airport is not always the cheapest option on paper, but it can still be the better deal once you add everything up.
City rental offices sometimes show lower prices, but you also need to consider the airport transfer, taxi or public transport costs, extra time, and the hassle of collecting the car later.
From our experience, airport pick-up has often made more sense because we could start the trip straight away and avoid paying separately to get into the city first. Before booking, we always compare both options with the real total cost in mind, not just the rental price.
5. Adjust Your Pickup and Drop-Off Times
This is one of those small details that can quietly change the final price. Car rentals are usually counted in 24-hour periods, so returning the car even slightly later can sometimes add another full rental day.
We always check the pickup and drop-off times before confirming. Sometimes we even wait an extra hour at the airport after returning the car, just to avoid paying for one more full day that we do not actually need.
6. Compare Insurance Options Before You Arrive
Car rental insurance is one of the easiest places to overspend, especially when you are tired after a flight and someone at the rental desk starts explaining worst-case scenarios.
We have often felt under pressure at the counter, and in our experience, adding extra insurance there is usually more expensive than arranging it before the trip.
That’s why we prefer comparing the options in advance. DiscoverCars offers Full Coverage, which we usually add to our bookings for extra peace of mind.
Recently, we also found another option, CarInsuRent, a third-party car rental excess insurance provider that can sometimes be cheaper than adding Full Coverage through the booking platform.
Whatever you choose, always read the policy details carefully so you understand the excess, exclusions, claim process, and what is actually covered.
7. Calculate Whether to Rent or Bring a Child Seat
If you are traveling with a child, always check the child seat cost before every individual trip. On some rentals, adding a child seat is simple and not too expensive, but on longer trips it can quickly become one of the biggest extras.
Bringing your own seat can be cheaper, but not always — especially if your airline charges extra baggage fees or if carrying it through the airport would make the trip more stressful.
We compare both options before booking instead of assuming one is always better.
8. Skip Extras You Can Replace Yourself
Rental companies often offer extras like GPS, Wi-Fi devices, or other add-ons that sound useful at the counter but can make the booking more expensive. On our first car rental trips, we were not fully prepared, and navigation was one of the things that made us feel more stressed than it should have.
Now we always bring a phone holder, download offline maps if needed, and use our phone for navigation. It is a small thing, but it makes driving in a new country much easier and helps avoid unnecessary rental add-ons.
9. Check Mileage and Driving Restrictions
Mileage limits are easy to overlook, but they can make a cheap rental much more expensive if you are planning a road trip. We always check whether the car includes unlimited mileage or if there is a daily limit, especially when we know we will drive long distances.
It is also worth checking driving restrictions before booking, such as cross-border rules, ferry restrictions, island limitations, or extra fees for driving in certain regions. A rental can look like a great deal until you realize it does not actually fit the route you want to take.
10. Photograph the Car Before and After the Rental
This does not lower the booking price, but it can save you from paying for damage you did not cause.
Before driving away, we always take photos and videos of the car from every side, including the wheels, windows, mirrors, interior, dashboard, fuel level, and mileage. Even if we have a good insurance.
We do the same again when returning the car, especially if the office is closed or the return process feels rushed. It only takes a few minutes, but having clear proof can make a big difference if there is a dispute later.
Final Thoughts
Saving money on car rental is not only about finding the cheapest daily rate. From our experience, the real savings usually come from checking the full price, comparing insurance options before you arrive, avoiding unnecessary extras, and understanding the rental conditions before you book.
We used to find car rental stressful, but having a simple process now makes a big difference.
We compare prices, check supplier ratings, look at the total cost, prepare the small things we need for the trip, and always document the car properly. It does not make renting a car completely risk-free, but it does make the whole process much easier and less stressful.
