Dear Cadillac Owner:

Records available to Cadillac Motor Car Division indicate you are the owner of a 1987 Brougham.

Cadillac has determined that your vehicle may have been built with an incorrect speedometer driven gear. This condition will result in the speedometer indicating lower than actual vehicle speed.

Please contact your Cadillac dealer to arrange for a service date to correct this condition on your vehicle. Your dealer will install a new speedometer driven gear. This service will be performed at no charge to you.

Instructions for making this correction have been sent to your Cadillac dealer. The labor time to install the new gear is approximately fifteen minutes. Please allow additional time for your dealer to process your vehicle.

The enclosed Campaign Owner Identification Card identifies your Cadiffac. Presentation of this card to your dealer will assist in making the correction in the shortest possible time. If you have sold or traded your vehicle, please complete the postage-paid card and return it to us. This will assist us in assuring all affected vehicles have been corrected.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
