    Buick LaCrosse — W-body / GMX365 (first generation) (2005–2009)

    The first-generation LaCrosse was a Buick sedan on GM's W-body (GMX365) platform, built at Oshawa, Ontario for the 2005 to 2009 model years and sold in Canada as the Allure (Wikipedia; the lists print the Oshawa plant code OST). GM's own option lists are in the archive for every year from 2005 through 2009. They show the 3.8 L L26 and 3.6 L LY7 V6 engines, with the 5.3 L LS4 V8 of the LaCrosse Super in 2008 only, and the NICB VIN manuals name the CX, CXL, CXS and Super series. The lists carry no trim availability, so the rows show years only; the 2005 and 2006 lists and the 2007 to 2009 lists differ in wording, not in meaning (except V73, which the 2005 and 2006 lists print with V78's wording).
