To recognize the Buick LeSabre's successful 10-year sales record as the best-selling full-size car in America, and to celebrate Buick's centennial anniversary in 2003, Buick has added a new trim option for the LeSabre Limited model. Buick's product planners must have been feeling particularly creative when they named it; it's called the Celebration Edition. It features a new monochrome emblem, a blacked-out grille and license plate pocket and two new premium paints, Crimson Pearl and White Diamond. Additional Celebration exterior bits include body-color lower fascias and rocker moldings, turn-signal indicators in the side mirrors and new 16-inch chrome-plated aluminum wheels. Interior refinements are limited to two-tone leather seating and Black Cherry wood grain trim. It also includes a number of otherwise optional features, such as StabiliTrak. The rest of the LeSabre line is pretty much unchanged, with the exception of XM Satellite Radio, which is a new option on the Limited, and side-impact airbags, formerly standard on all LeSabres, are now optional on Custom models.
