Individual flexibility during summer holidays is highly valued by many travelers, but renting a car can involve significant price differences and bureaucratic pitfalls.
A recent survey by the Upper Austrian Chamber of Labor shows that rental car prices in popular European holiday regions for the peak season in August 2026 can vary by up to 135 percent. Besides the rental costs themselves, insurance terms, deductibles, and the booking method play a crucial role in the overall cost of a reservation. Consumer advocates recommend comparing offers well in advance from home, carefully reviewing contracts, and insisting on complete documentation of any existing and new damage on-site to avoid unexpected additional costs.
Analysis of price structures in European holiday regions
For the price comparison, the Upper Austrian Chamber of Labor analyzed the online rates of six established car rental companies for a one-week rental period in the first week of August 2026. The research focused on 18 holiday destinations in Southern Europe, including the Greek islands, Cyprus, Sardinia, Sicily, and popular coastal areas in Spain, Portugal, France, and Croatia. The search was for the cheapest available vehicle category, including unlimited mileage, all applicable taxes, and theft and damage protection packages.
The results highlight significant regional and provider-specific discrepancies. The lowest rental prices for vehicles without a financial excess in case of damage were found on Gran Canaria, where the cheapest car during the survey period was offered for €213 per week. In other Mediterranean regions, particularly in France and on the Italian islands, the starting prices were considerably higher. In the majority of the holiday destinations surveyed, the rental company Sunny Cars offered the most competitive prices for vehicles without an excess in case of damage.
The role of the deductible in comprehensive car insurance
A key factor in evaluating rental car offers is the contractual arrangement of the insurance. While tariffs with a deductible often appear lower daily rates at first glance, they pose financial risks for renters. In the event of an accident or vandalism, customers with deductible contracts may have to pay up to €2.900 out of pocket, depending on the provider and vehicle class, according to available data.
A comparison of the cheapest offers for each destination shows that waiving the excess adds an average of about €120 per week to the cost. Consumer advocates point out that this additional expense must be carefully weighed against the benefits beforehand. While full coverage protects against unexpected additional charges, especially when driving in narrow towns or on unpaved roads, it significantly increases the base rental price.
Risks of online platforms and alternative booking methods
In its analysis, the Upper Austrian Chamber of Labor also addresses the choice of booking channel. Travelers are advised to book directly with the actual car rental companies or through established club offers whenever possible. While purely online booking platforms and comparison portals often lure customers with low introductory prices, they frequently prove to be of little help in the event of subsequent cancellations, rebookings, or damage claims at the holiday destination, as they usually only act as intermediaries and refer customers to the local rental company.
An exception are offers from automobile clubs like the ÖAMTC. Their own booking portal allows price comparisons from major international rental companies such as Avis, Europcar, Enterprise, Hertz, and Sixt. The rates displayed there generally already include comprehensive insurance coverage without a deductible. Furthermore, members often receive discounts of up to 5 percent on the regular rate for these bookings, which increases cost transparency.
Contractual provisions and protection against double insurance
To avoid unexpected extra costs when renting a car on vacation, consumers should carefully review all clauses in the contract before signing. In addition to the liability insurance coverage amount, important details include the minimum age of drivers, any additional fees for other registered passengers, and the applicable fuel policy. Agreements such as a full tank of fuel upon pickup and return are generally considered the clearest.
At rental car counters, it frequently happens that staff try to pressure customers into purchasing additional, paid insurance. If comprehensive coverage without a deductible has already been arranged in advance, further policies are usually unnecessary. Travelers should not be misled by claims of supposedly insufficient coverage and should avoid taking out duplicate policies.
Vehicle handover and documentation upon return
Another important step to avoid disputes is a thorough inspection of the rental car upon pickup at the rental station. Any existing scratches, dents, or defects in the interior must be recorded in writing on the handover report and initialed by the rental company employee. It is also advisable to document the vehicle's condition during the day with photos or videos on your own mobile phone.
When returning the car after the rental period, a written return protocol should always be requested, confirming the vehicle's flawless condition. If the car needs to be parked outside of opening hours and no staff is present, comprehensive insurance without a deductible, purchased in advance, offers the greatest protection against subsequent claims and disputes regarding newly incurred damage.
