Advantages: None

Disadvantages: Terrible all around, would rather walk across Europe

Terrible experience with our 11-day rental, a nightmare that just doesn't want to go away. On the day we picked up the car, we realized they would make every attempt to keep the $500 pre-auth deposit (damage deductible) - and that's exactly how it worked out.
We returned the car in an immaculate shape and there were absolutely no notes on the condition of the car on the return form. However, the electronic key gave us trouble throughout the trip and we were even stranded in Greece for almost a whole day without any roadside assistance provided by Sixt. Instead, they saw an opportunity to charge for the key itself (even thought there was no visible damage on it) - and the arbitrary price for it so far has been CAD$1,200!!!!!!!!!!!!!!
They debited $800, returned $385, then took out another $800 - even though the total authorization they had was for $800 (or 500 EUROS).
Now that we are back home, noone is taking responsibility - even though we rented from a Sixt outlet in Skopje and our contract clearly said Sixt on it, without any other company names.
But Sixt says - sorry, you have a contract with our supplier in Skopje and they hung up on me 3 times. Promised to have supervisor call me back within 48 hours and that was weeks ago.
The worst car rental experience ever, complete lack of accountability, it's border line fraudulent business.

Summary: Sixt - NEVER AGAIN
