A percentage residual value guidebook gives the value of the base vehicle stated as a percentage of the manufacturer's suggested retail price (MSRP) for the desired lease term. The MSRP of any dealer-added equipment that is listed in the guidebook must be added to this amount to get the adjusted MSRP.

SPARK SPORT UTILITY	12 Mo.	24 Mo.	36 Mo.	48 Mo.	60 Mo.
1. 2d Wagon 4WD	68%	58%	50%	42%	34%
2. 4d Wagon 4WD	70%	60%	53%	45%	37%
3. 4d Cargo 2WD	50%	45%	40%	35%	30%
Add for CD player	$250	$200	$150	$100	$75
Add for moon roof	$450	$400	$350	$300	$250
Deduct for no cruise control (except model 3)	$100	$100	$100	$100	$100

Follow these steps to determine the future value of a new 4-door (4d) Spark Sport Utility 4-Wheel-Drive (4WD) Wagon for a 3-year period of ownership:

1. Find the MSRP (window sticker price) of the vehicle before any deductions are made (for example, deductions for a special equipment package). Assume that the MSRP is $29,475.

2. Determine if any equipment is being installed by the dealer. Add the MSRP of these items, but do not exceed the maximum amounts shown in the guidebook. For example, assume that the dealer is adding a sliding moon roof and CD player. Add those items:

Base MSRP	$29,475
Plus dealer-installed equipment:
Sliding moon roof	+ 350
CD player	+ 150
Equals adjusted MSRP	$29,975

3. From the table, find the base residual percentage for the vehicle for the 36-month term. In this example, assume it is 53%.

4. If the initial mileage on the vehicle is more than the stated number of miles at lease inception in the guidebook (for example, 500 miles) or if the lease's annual mileage is different from 15,000 miles a year, find the table for the mileage adjustment and the percentage to add to or subtract from the base percentage. For example, if the mileage allowed in the lease is 12,000 miles a year but the guidebook is based on 15,000 miles a year, assume that the mileage adjustment for a 36-month term is 2%. Add this percentage to the base residual percentage to get the adjusted residual percentage: 53% + 2% = 55%.

5. The 3-year future value is the adjusted MSRP times the adjusted residual percentage: $29,975 x 55% = $16,486.25.
