Who is Sixt?

Which? verdict

Considering it is one of the more expensive providers in our survey, Sixt’s poor customer service rating is disappointing.

What’s Sixt like?

With more than 100 years of car rental experience, you’d think that Sixt would have learned the value of good customer service by now. Sadly, its ratings didn't show that as it scored a measly two stars out of five.  

A common complaint was the length of queues and ‘staff shortages’ leading to extended delays. One customer told us that it ‘ruined our weekend plans’.  

Multiple customers also told us they felt under pressure to purchase Sixt’s own additional insurance, even if they had already purchased cover. One customer said they were repeatedly told that they would be ‘left with huge bills’ in the event of an accident. 

At an average of £56 per day, Sixt was the joint most expensive provider in our survey (alongside Enterprise).

It wasn’t all bad, though. A five-star score for the age, condition and mileage of the cars suggests that its claims of a high-quality fleet are founded.

Should I book with Sixt?

No. It's expensive and its customer service is poor. Alamo and Enterprise are better alternatives for global car hire.
