Sales in America were initially strong, due to the appeal of classic 'British' interior design, combined with a clean and up to date exterior design, both of which compared well with its sister the
Acura Legend. U.S. sales hit a high of just over 14,000 cars in 1987. All models came with extensive, real wood interior trim. The SL models also feature ABS, power Connolly leather seats, and two-tone paint as standard equipment. U.S. market Sterlings got motorized automatic seatbelts in the 1989 model year. While dynamic characteristics and performance were broadly similar to the
Legend, due to the shared platform, core structure and power units; detail spring and damper changes gave each model its own unique feel. The Sterlings were the sportier cars, with less float and an overall tighter feel than the Acura Legends. The ride/handling compromise was defined through the shared use of Honda's double wishbone front suspension that allowed a very low hood line, but offered limited wheel travel. This meant that on poorer road surfaces, there was a greater possibility of reduced traction. Early build quality of the 800 was demonstrably poor as measured by
J.D. Power. The various problems included issues with interior trim – for example, the hood latch remained on the passenger side of the cabin the first year in production – problematic
Lucas electronics, and paintwork. Corrosion problems in early models would also mar its reputation. All of this contributed to the eventual demise of Rover in the United States. The Sterling fell to the bottom of
J.D. Power surveys, while its twin, the Japanese-built
Acura Legend, had enjoyed top rankings its first year. During its run, the instrumentation had been changed to gauges sourced from a different component builder (losing the oil pressure gauge and voltmeter in the process) and build quality had started to improve year to year. However, these changes were too late to prevent the U.S.-market version from later being withdrawn due to poor sales. ==Discontinuation==
