I have rented from HERTZ for many years without any issues in the US as well as in Europe.

Now I will be going to Denmark, and pay myself, for one month and find SIXT's quotes to be much lower than HERTZ.

At the same time I have read horror stories about being overcharged even for minor scratches and staff being rude etc.

What is your opinion, take the risk and save $ 300+ or stay with HERTZ or another major company?
