Smooth

I've booked Corolla n got a similar one Kia which i felt was a downgrade and the car condition was not the best...right side of the car had lots of scratches and dented and the lady at newark was super gruchy, not friendly at all. However, return at Albany Airport, the staff was much more helpful and friendier

so far nil

It was the first time my car was downgraded, which was frustrating. However, we left quickly because we had other plans.

Pretty good.

I had to wait in line for an hour, which was a bit long. Also, the car rental company in Los Angeles was very sneaky. Despite me saying I didn't want any additional services, they added an extra charge, which I didn't notice until I drove off. The next day, I called the rental company's customer service to have them contact the LA branch to cancel it, but they said it couldn't be done. Eventually, I called Budget customer service myself and got it canceled.

Not bad
