I have the same problem. I was in Milan in October 2010. I got a car from Auto Europa Silicy by car company. It was Nissan Micra 1.2. 7 days car haven't got any damages and problems. We was in many cities in Italy, about 2000 km was done for 1 week. After we gave car back (i gave keys in office to a man, he said nothing needed more, we don't checked car, it was 2 hours on parking when we waited for office opening) and when we arrive to out home country I checked internet bank and saw that there were charged 860 EUR more (first 1200 eur charging was still there, not unblocked). I called to Auto Europe and they said that car was damaged and this 860 EUR deposit is for repairing. After 2 weeks they unblocked money but not all, minus 380 eur for mirror repair.
Also I find real prices for repair. They prices are fake. Mirror cost is only 80 eur in Italy not 180 Eur like they send me some fake papers. You can see them in attachment.
So I recommend to all people, if you get car in this company you need full insurance + photo car when you gave it back + check car with office man so they can`t charge you more and damage car after you gave it back like it was with my car.
Better to get car from avis, Hertz, europcar and pay more. It will be your mistake if you want lower cost for car hire in Italy. They are SCAMmers, they will fraud your credit card and charge from it without your knowing.
