After renting a car at Ljubljana airport in august 2019, during check out, a scratch as been detected under the front bumper.  Not indicated during the check-in and unobservable for me at this moment even with some pictures. I declined to be responsible of this problem, and I'm sure that is a trick to increase the total price of the rent.  I expressed my displeasure but with the pressure from the SIXT manager and the stress of missing my plane I unfortunately have been forced to sign the report. I believe I'm a victim of a SIXT pudding scam... Even more I'm sure the repair won't take place and this ruse will be repeated with other customers. I'm young and I'll never use Sixt again in my life.  So now they are asking me 270€ and I don't know what to do. I really find these business practices dishonest...
