I have to admit I was a tad worried after seeing the previous reviews. But can say now after my experience that I felt nothing but good things. I needed just something with four wheels to get me around for wedding apts and Fox was $100 less than its competitors. Our car was tiny and nothing special but we knew that upon reserving. I have learned to just say no to everything they ask (since my current insurance covers rentals) and so the process was quick and painless.
The only complaint or rather con is that they require a $150 deposit that is deducted when you get the car and is returned when you bring it back. It is not a big deal as long as you are aware they do this. I returned the car yesterday and have yet to see the deposit back so I would definitely plan on a few days before seeing the money back in your acct.
All in all I would go with Fox again! Recommend for those just looking for a car to get them around.
