Thrifty Car Rental and Dollar Car Rental are, when you get down to it, actually owned by the same company. This means that even if the two companies donat have joint Christmas parties, ultimately, they arenat wholeheartedly competing. Thrifty has fewer New York City locations than many of the other international car rental companies. They also rent parking spaces but not in New York City. The Thrifty fleet is broken down into 14 categories ranging from full-sized vans to small economy cars but you have to be over 25 to rent at regular rates. If youare 21-25 years old, youall incur an extra fee because youare young.
