drive model in 1985 and named it simply the Fleetwood. Compounding the confusion, the optional "d'Elegance" package (introduced in the upscale Fleetwood trim line in the 1970s, offering even more luxurious appointments, including button-tufted seating and rear-seat reading lamps), was available on and appended to the names of both models, resulting in a traditional body-on-frame/rear-wheel drive "Fleetwood Brougham d' Elegance" and a unibody/transverse engined "Fleetwood d' Elegance". The solution was dropping the term "Fleetwood" from the rear-wheel drive model, leaving just the "Brougham". Since it was body-on-frame, it was popular among coachbuilders who manufactured stretched limousines, along with the similar but somewhat smaller Lincoln Town Car, as well as traditional Cadillac buyers who preferred the familiar combination of exterior size, heft, and rear-wheel drive. This was the last Cadillac to be produced without airbags. Description The 1987 Brougham was built at the Clark Street Cadillac Assembly Plant in Detroit, Michigan, as the Fleetwood Brougham had been in 1985-86. Before the shift to the Arlington Assembly plant in Arlington, Texas, some early model year 1988s were produced at Detroit Assembly in late 1987 before the plant's December closure, and construction continued at Arlington through 1992. The 11th digit of the VIN indicates plant assembly. A "9" as the 11th digit indicates a Detroit Brougham; a "R" indicates an Arlington Brougham. Many of the Arlington assembled examples also had a state of Texas/GM Arlington decal on the rear side quarter glass. VIN "9" Broughams were produced 1986-1990 and, although rare, can be found as "commercial chassis" vehicles, and generally have a higher output Oldsmobile 307 LG8 Engine and different transmissions (typically the TH400 three speed), depending on the use. Generally speaking, minor differences between 1987 and 1988 (VIN 9 and Y) can be found, such as carburetor assembly. While these cars all used Rochester Quadrajet Electronic four-barrel carburetors, differences include an electronic (Detroit) versus vacuum (Arlington) Idle Load Compensator, as well as an electronic (Detroit) versus climactic (Arlington) choke system. The vin "9" engine is the high output version of the base LV2 307 vin code Y and shares most parts with it. The HO engine is the same engine that was used in the rear wheel drive Oldsmobile 442. While the engine was not powerful, it proved to be a reliable engine with proven, but dated, technology. The Brougham wore a cross-hatch grille in 1987 and 1988 which was an identical
