Car rental tips: avoid the common traps
The biggest avoidable costs when renting a car are a high insurance excess, unfair fuel policies and counter upsells. Book all-inclusive with zero excess, choose full-to-full fuel, photograph the car at pick-up and return, and check local rules such as low-emission zones and electronic tolls.
Book early for the best price
Rental prices rise as availability drops, especially in summer and on islands. Free cancellation means you can lock in a good rate now and rebook if the price falls.
Choose full-to-full fuel
A full-to-full policy (collect full, return full) is fairest. Avoid “full-to-empty” deals where you pre-pay for a tank and lose any fuel you don’t use.
Photograph the car at pick-up and return
Take dated photos and a short video of every panel, the wheels and the interior. It is your best protection against disputed damage charges.
Understand the excess before you drive
With zero-excess cover you are protected from the first euro. Without it, check exactly how much you would be liable for.
Decline counter upsells you already have
If your booking is all-inclusive, you do not need the desk’s excess-reimbursement insurance. Be polite but firm.
Check what counts as an “extra”
Child seats, additional drivers, GPS and winter tyres are usually paid extras. Add them when booking to guarantee availability.
Know the local rules
Low-emission zones (Spain, France, Germany, Italy’s ZTL) and electronic tolls (Portugal) can mean fines weeks later. Check your route.
Use online check-in
Completing paperwork before you arrive saves time and reduces the chance of upsells at a busy airport desk.
Frequently asked questions
Is it cheaper to rent at the airport or in town?
Airport desks are convenient but sometimes carry a surcharge. An all-inclusive price already includes airport fees, so compare the total price rather than the headline rate.
Should I take photos of the rental car?
Yes - always. Dated photos and a short video at pick-up and return are the simplest way to avoid being charged for pre-existing damage.
What is the most common hidden cost?
A high insurance excess. It does not appear in the headline price but exposes you to hundreds or thousands of euros. Zero-excess cover removes it.
