Very disappointing experience with Sixt at Vienna Airport.
Timeline of events:
• 14 Mar 2026, ~9:40 AM (Pickup at Vienna Airport
At the counter, I was informed by the staff that the vehicle (Mini Cooper) I booked was unavailable and I will be provided a “free upgrade.” Based on this, I agreed and signed the rental agreement.
• During signing
There was no clear explanation that the upgrade was chargeable. Given the fast-paced airport environment, coupled by my long 12.5 hrs flight and 2 toddlers in tow, I relied on the staff’s verbal assurance.
• After reviewing the contract after I return the car
I discovered a charge of EUR 674.80 for “Choice Upgrade” — a significant cost that was never disclosed or explained upfront.
Key issue: This is not a minor misunderstanding. Being told something is free when it is actually charged — especially at this amount — is highly misleading.
The charge was:
Not clearly explained
Not presented as optional
Not transparently communicated before signing
Why this matters: Customers should be able to trust what is told at the counter. This experience raises serious concerns about transparency and sales practices.
Current status: I have formally disputed this charge and escalated the matter to consumer protection channels.
Advice to others: Be extremely careful when renting here.
Do not rely on verbal assurances — check every line item before signing.
I hope Sixt reviews this case seriously and improves transparency for future customers.
