Deciding on which vehicle to lease is the predominant factor in ascertaining the cost of monthly payments to the leasing company. Obviously, a bigger, more expensive vehicle will generally cost more in monthly payments than a smaller, cheaper vehicle. If the choice you have to make is between 2 vehicles of the same value, then you must research the depreciation rate of the 2 vehicles as the vehicle that depreciates at a lower rate will command more value at the end of the lease agreement and therefore will cost you less in monthly payments.
