Some vehicles have features that may be considered a standard option for one specific model but they may also be available on another model, but for an additional charge.
These are referred to as a Regular Production Option or RPO.
This list includes options available on all of the 1984 to 1987 Buick Regal models.
Some options were available in one or more production years but not all of the years.
