Renting a car regularly can be expensive. But going car-free and renting only periodically—for the odd road trip, for example—can sometimes be more cost-effective than buying a new car. Another option is to rent a car occasionally and buy an inexpensive used car to rely on the majority of the time. With the right planning, you may be able to save a significant amount by renting a car. Read on for five scenarios when you should rent a car instead of buying one. In many cases, public transportation may be more efficient than trying to drive a car in traffic. Since public transit conserves land, encourages mixed-use development near transit stations, and promotes ride-sharing, it often reduces the distance, time, and fuel it takes to reach your destination. If you plan a road trip or need a car for a day in such a city, renting a car occasionally can be cheaper than buying a car. For example, a one-day compact car rental in Boston in February 2020 can run you around $58 at Thrifty Car Rental or $56 at Enterprise; multiply that by 12 to get an approximate yearly cost of under $700. The average compact car costs a whopping $22,000 as of January 2020. If you add the cost of car insurance, paying for a parking permit or parking meters, and a designated parking space in addition to your rent, it may not make sense to own a car at all. This may be a good idea if you do not own a car, the car you have is not very reliable, or your car is capable but you would prefer to put the mileage on another vehicle. It’s common for companies to provide what is known as a collision damage waiver; if you pay for this coverage and get into an accident during the road trip, the company will file your insurance and foot the bill for the repair without causing your personal insurance premiums to increase. It can be fun to choose a new or a different car model than what you are accustomed to driving; you can treat the rental as an extended test drive while on your road trip. This can help you make a more informed purchase when you decide that it’s time to buy a car. You can potentially save money on these rentals via a motor club such as AAA, a professional organization, or alumni associations. Also considering booking a car through a travel website or bundling your hotel and airline tickets to find deals. Be aware: It’s more expensive to rent a car when you are under 25 years old, so budget a little extra when evaluating the cost of renting a car versus buying one if you’re under this age. Many car rental companies provide roadside assistance, which means you’ll have the added protection of the rental company helping you out if the car were to break down on the road in an unknown location. Renting a car instead of using one you bought is a particularly worthwhile option if there are several people you are traveling with and you will not all fit into one car. Alternatively, you can rent a large van to travel together and split the cost. For example, you could designate a half-day or day every week, or even just a weekend every month, to carry out all your administrative tasks, such as going to a grocery store, post office, bank, or gym. Likewise, rent a car to buy a large, one-off item, such as a television. This option could wind up being cheaper than paying to ship a large item to your home. To increase the money-saving potential of this arrangement, split the cost of the rental with friends if you have several people who need to run errands at a time. By coordinating your efforts, you can all save money and help each other out. Renting a car occasionally during the year could save you money compared to buying a luxury automobile to use every day. For example, a two-day luxury car rental in New York City in June 2020 would cost around $202 at Thrifty Car Rental and $227 at Enterprise. Buying an average entry-level luxury car costs $40,000 as of January 2020. If you rent through a car service, look online for a Groupon deal or an event discount. These discounts may qualify your guests for reduced rates on rentals for occasions such as weddings or family reunions. Updated by Rachel Morgan Cautero.
