What made the Signature Premium so premium had to do with accessories rather than performance. It received the standard 220-horsepower V8 (as opposed to the performance-enhanced edition with 15 more horses), but it came equipped with items that were either optional or unavailable on other Town Cars of that year.

Those items were a sunroof and an upgraded audio system featuring a CD player with changer as well as a subwoofer for those retirees who like to crank the tunes. Heaters for the front seat were optional, as were daytime running lights, to make the big sedan extra visible on those two-lane cruises.
