Yes, I have used Europcar and Enterprise and PCO Rent.
Europecar was horrible in that, every time I went to their office, they were understaffed and would wait approx 3-4 hours after my appointment time before I could leave with a car.
Their cars had numerous problems and one they gave me was exceptionally dirty and had body work damage all over it.
I needed to work that night so I took it, but I took photos of everything before driving it away.
The car stank and it was horrible, like dried soup had exploded in the car. I returned it the next morning and cancelled the agreement.
They sent me an email trying to charge me for the damage. Thank god I took the photos. The office I dealt with didn't want to know as it was a different department that deals with damage, only when threatened with court action and geo-tagged meta-data in the photos as proof did they drop it without so much as an apology. I saw other people angry with them too in their office. I would never rent from them again.
Enterprise, they don't check or clean their cars over well, twice I had cars with low oil warning lights, car with slow puncture on collection, they promised to reimburse me for some of my loss of earnings. It never happened.
I don't trust these companies any more. PCO rent was one of the best for the Prius so far, but more expensive than the quotes on here. £250 ish.

6. After that it's hard to rent a car or get insured.

We should make a list, top 10 exec companies and vote for it?
