As with new car-leasing, your price research should focus on the key
figures that are the initial market value and the estimated residual value
of the used car. This is harder to predict since there is no factory-set
sticker price on used cars, and the residual percentage is very much pegged
to a subjective current retail value. Use different sources to get a rough
idea of the value of the used car: your local dealerships, internet
car-evaluating tools, such as Edmunds.com and Cars.com, to name but a few.
Another way to pin down a good estimate is to compare the lease on your
given car to a lease on a new-car with the same make and model. This should
give you a better picture of the difference between leasing new and going
for used. Just like leasing a new car, used vehicle leasing is more
attractive when residual values depreciate the least. You stand a better
chance of finding a bargain in the high-end, luxury vehicles that keep
their values better as used cars.
