Hello Kitty-
It’s difficult to recommend without knowing your location, mileage requirements and number of passengers (vehicle size requirement).
In Brooklyn, I’ll recommend:
Speedy Rent A Car
4515 18th Ave , Brooklyn
NY , US , 11204
Phone: 718-871-1100
My recommendation is based on personal experiences dealing with them.
The place is run by two Chasidishe brothers, Abe and Yanky.
They are pleasant, accommodating and extremely honest.
I’ve dealt with them several times over the years (their collision shop, too), and have always been satisfied.
If you have a high-mileage trip planned, make sure to reach an accommodation beforehand; i.e. pay a little more and don’t get socked with a mileage fee.
