$350 per day for an economy class car?!

Rented a Versa from their San Diego office - a black car in a very dark parking lot. Found a dent above a front tire the next morning. They charged me the rental fee of $70-something for 3 days, plus put a $250 charge on my credit card for my deductible. They never contacted me directly afterwards though they said they would the next week. Two months later they tell my insurance company that the repairs will be $1800; the car had many additional miles on it and the repairs specified shouldn't have been necessary for the damage involved. Yesterday I found that they'd charged another $750 to my credit card without my authorization, making my three days come to over $1,070. This kind of corporate behavior is inexcusable. They never provided proof, via previous check-in slips from previous rentals of the vehicle, to show that the damage occurred with me originally, nor did they provide my claims dept. with a legible picture of the damage (I had to do that). Their failure to deal with me directly speaks a lot about their corporate practices. Choosing this company for supposedly low rates would be the height of foolishness
