2.93 rear-axle gears and a limited-slip differential, heavy-duty cooling system including oil and transmission coolers, and a factory-installed self-leveling rear suspension called Dynaride, which consisting of air shocks, a height sensor between the rear axle and body and an on-board air compressor. Most visibly, a pair of electric fans offset to the left under the hood was replaced by the combination of one conventional fan-driven mechanically from the engine alongside one electric fan. Body The Roadmaster Estate wagon shared its body with the Caprice Estate and Oldsmobile Custom Cruiser; common styling features included the Caprice's headlights and the Custom Cruiser's 2nd-row "Vista Roof" with a sunroof. Simulated woodgrain sides were standard, though the treatment could be removed for credit. All three wagons offered an optional rear-facing third-row seat, bringing seating capacity to eight. The Roadmaster sedan had a distinct fascia, featuring its own grille and headlights stacked above running lights and turn signals. It shared a formal sedan roofline with the Cadillac Fleetwood, but was nine inches shorter in length and six inches in wheelbase. The interior received a redesign for the 1994 model year which included new dual airbags, moving some instrument panel gauges closer to the steering wheel, and revisions to the radio and climate controls. The side-view mirrors were changed in 1995, changing from a "Lolipop" style mirror mounted on the door skin, to a new folding design mounted on the sail panel. The 1995 Roadmaster retained its skirted rear wheels (removed from the Caprice/Impala SS), while the sedan was updated with new bodyside moldings. Station wagons saw a shade for the Vista Roof along with a cargo cover. In 1996 automatic climate control became standard, and the rear seatbelts were redesigned with a "cinching" feature. Discontinuation In spite of a production run of over 200,000 Roadmasters in a six-year span, a combination of overcrowding among Buick's high-end sedans and pressure from full-size SUVs on the Estate wagon led to GM focusing on higher profit margin vehicles, such as pickups and the truck-bodied Chevrolet Suburban. In 1996 the Arlington Assembly facility in Texas was converted to assemble both SUVs and pickup trucks, leaving the Roadmaster without an assembly line. The final vehicle was produced on December 13, 1996. All 1996 Roadmaster Estates received a "Collector's Edition" hood ornament in place of the traditional tri-shield Buick badge.
