Pros and cons of leasing
Buying a vehicle is a fairly straightforward process. You borrow money from a lending institution, pay the dealership for the car, and then make monthly payments on the loan until it's paid off. As you pay off the loan, you gain equity in the vehicle until it's eventually all yours. You can keep the vehicle as long as you like and you can do whatever you want to it, from giving it a custom paint job to entering it in a demolition derby. The only penalty for modification or abuse, perhaps, is a lower resale value when you're done with it.
Because you're typically paying back the entire cost of the vehicle (less any trade-in or down payment amounts), a loan's monthly payments are higher than when leasing. And when you're ready to get a new car, you need to either trade-in or sell your old one.
On the surface, leasing appears even simpler. You pay the leasing company a monthly payment that's lower than when buying. Then, after enjoying the most trouble-free two or three years of the vehicle's life, you simply bring it back to the dealership and lease another new one, or walk away. No muss, no fuss, right? Gone are your worries about haggling over the trade-in value or how to sell your old car. With a lease, that new-car smell need never leave your nostrils. Moreover:
There's often no down payment required when leasing, or only a low one.
You can drive a higher-priced, better-equipped vehicle than you might otherwise be able to afford to buy.
You're always driving a late-model vehicle that's usually covered by the manufacturer's warranty.
As attractive as a lease appears, however, there are a number of disadvantages:
Leasing typically costs you more than an equivalent loan, in part because of higher finance charges.
Once you're in the leasing habit, monthly payments go on forever. In contrast, the longer you keep a vehicle after a loan is paid off, the more value you get out it.
You have a limited number of miles in your lease contract, typically 12,000 to 15,000 miles a year. If you drive more than that, you'll have to pay an excess mileage penalty of 10 cents to as much as 25 cents for every additional mile. On the other hand, if you drive too little, you don't get credit for the unused miles.
You must maintain the vehicle in good condition, or you'll have to pay excess wear-and-tear charges when you turn it in. So, if your kids are apt to turn the interior into a finger-painting studio or your car's a magnet for parking lot dents and dings, be prepared to pay extra.
If you need to get out of a lease before it expires, you may be stuck with thousands of dollars in early termination fees and penalties-all due at once. This could equal the amount it would cost had you stuck with the lease for its entire term.
You can't customize your vehicle in any permanent way. In addition, arranging a lease can be a confusing complicated process that can easily leave you paying more than you should.
It's important to consider these pros and cons very carefully. You can also use the Documenting the deal worksheet to crunch the numbers for a particular vehicle both ways to see which makes the most sense.If you want low monthly payments but are concerned about the limitations of a lease, consider buying a less expensive vehicle or a well maintained used car, or getting a longer loan term (although there are risks to this).
