Car was ok, glad that received diesel car, what is more economical.

All good.

Overall service was pretty good, but the contract did not state that the fuel level at return must match the level at pickup. When we got the car, it only had two bars of fuel, not a full tank. This made it hard to gauge how much fuel to add when returning the car. We ended up having to pay an extra 15 Euros because the tank was slightly underfilled. Other companies operate on a full-to-full policy. I can't help but feel there's a bit of trickery involved.

Car was a bit old (peugeot 301) but in good condition. Multimedia was very basic without support of carplay/android auto. Staff was ok.

Car was older and had some servicing problems, was not a very smooth ride

Picked up from Athens airport at night. Red flags went up right away at terminal counter. Online we went for VW Golf, but Avance employee told us we would be getting Mercedes A Class and showed us a picture highlighting features. She started pitching additional coverage complete with old school calculator to illustrate potential cost savings in the event of an accident. As soon as we told her we had already purchased coverage online, Poof! suddenly the Mercedes was no longer available because "it was not returned in time by the previous renter" so we were back to a Golf. At the rental car center where staff was sparse and reeked of cigarette smoke, the Avance employee was friendly enough but in crowded parking lot made a big show of going over the car carefully to make note of its condition. We commented that it was hard to tell if he would have a complete record of the many minor scratches as well as some cracks in lights on the vehicle in the poor lighting. He insisted they have a full history of the condition in their systems and that the most minor scratches would not be an issue. He tried to put us at ease, but we were concerned having never gone through this kind of thing when renting from major companies. We returned the car in the afternoon, and when an employee came to check the gas level, etc. we were told there was a problem. Again we waited. Finally we were told there was a new dent on the underside of the car. We objected that we had no problems and that the employee at pickup had definitely not examined the underside of the car with a flashlight so we could not know whether the damage was already there. Avance supervisor insisted their records did not show this damage. We went to look at car together, the supervisor found a scratch on the rear bumper he insisted was also new. After back and forth he walked way crumpling up the damage sheet and throwing it over his shoulder saying "I don't give a sh*t." At least he assured me we woul
