motor mounted inside the trunk latch. All models were now installed with Ford's Keyless Entry System, and an automatic dimming high-beam module. This worked via a sensor located adjacent to the rear-view mirror, and sensitivity could be adjusted by a dial located on the dashboard. The Mark VII was the first modern American manufactured vehicle to be equipped with a replaceable bulb headlamp system. Ford had petitioned NHTSA for a rule change permitting replaceable bulb headlamp systems, which was enacted in the summer of 1983 in time for the introduction of the Mark VII. 1985 was the last year for the Mark Series to include the "Continental" name as its nomenclature. The dealer-installed GTC performance option package is introduced (see below). As they have largely been replaced by cassette tapes, the 8-track tape player option is discontinued. An in-car telephone is added to the options list for $2,995 ($ in dollars ). Lincoln Mark VII (1986–1992) For 1986, the Mark series was integrated into the Lincoln brand after being within the Continental marque for 18 years, ending the naming confusion. The Continental Mark VII was renamed the Lincoln Mark VII and given Lincoln badges with the first three digits of the VIN changed from 1MR Continental to 1LN Lincoln. Other visual changes involved the addition of a federally mandated center brake light (CHMSL). The rarely-seen BMW diesel was dropped from the line, as was the Versace Edition. A number of changes were made for the LSC for 1986 to differentiate it from the rest of the Mark VII line. To update its performance image, the 1986 LSC was given analog gauges in place of the all-digital dash; the engine output increased to 200 hp. Largely unchanged from 1986, a running change late in 1987 production added the 225 hp 5.0L "H.O." to a limited number of LSC models. 1987 would be the last year the Mark VII offered an optional CB radio. Since vent windows had all but disappeared on American automobiles by the 1980s, the option for them was discontinued for 1987. For 1988, the Mark VII model line was revised. As the Mark VII carried a large list of features, the base-trim model was discontinued, leaving the luxury-oriented Bill Blass Edition and the performance-oriented LSC; both versions were priced the same. The 150 hp and 200 hp versions of the 5.0L V8 were replaced by the 225 hp
