    Cutlass Ciera — A-body (1982–1996)
    • 1985–1987 Single-source

      first offered as an option on the 1985 coupe, added to the sedan for 1986, replaced after 1987 by the International Series (Wikipedia's Ciera article, text and trim list agree); the article also prints "W45/W49" for the International Series 1988–1990, a slash form that names neither code, so those years are not claimed

    This page aggregates every documented appearance of W45 in the Oldsmobile reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
