Cons: Without consent or notification, my credit card was charged $200 when I picked up the car, then charged the $54 rental when it was returned the next day, along with another $200 charge. I contacted the number on the Budget receipt, who said those charges were "authorizations" and would come off. It's been 6 days, and still no pending transaction reversing the $400 in additional charges. They're also showing up in my credit card detailed billing as "purchase", not "authorization".
Pros: Pick up and drop off was very quick, I was in and out in less than 15 min both times. I paid $180 total for a week long rental of an economy car, which I thought was a very good value.
Cons: Economy car is economy. No remote door locks, very tiny car, lots of road noise, but what do you expect when renting this cheaply? On the plus side I ended up with a car that had XM radio. Usually this would cost an extra $6 per day, but I didn't ask for it so I didn't pay for it.
