Use window sticker, not what you paid??
There are different scenarios to look at.
1. Purchase Price $17,900 on January 19, 1988,
delivered Feb 11, 1988
2. Window Sticker = $18,751
Destination charge $430
Options subtotal $6,759
MSRP = $ 11,562
Warranty 72 month/100,000 miles $840, waste of money!!, my car only has 36,000 miles
3. Dealer add-ons and markups.
Now this doesn't include any extras as mentioned in other replies
Example applied or installed 1987/1988
Auto Armor Fabric Protection applied at 10 miles for $199.00
Ziebart Rust Protection and undercoating $330
New Keystone Turbo Rims (stored GN wheels) $425
After market alarm $230
PLUS I have the customer satisfaction basic new vehicle and pre-delivery inspection procedure completed 7/24/1987 and everything else for the car, originally from delivery 1988.
