The RPO (Regular Production Order) codes are located on your spare tire cover, driver’s side door, glove box, trunk lid or under the center console on most GM cars. Usually, the Buick codes are on the spare tire cover, or trunk lid. The pic below, is an example of the SPID/RPO code sticker from my car. The codes shown below have been decoded in the description list here. If you do not see a code for your options, you can post them here, or PM me with the codes. I will try to decode them and PM them back to you. I will also add any codes submitted here to the master list. Please include the year and model of your Buick!

To begin with, we started a description list for LeSabre, Click Here and Park Avenue, Click Here. We can also include Regal, Century, Riviera etc., if the owners would like to participate.
