featured a touchscreen computer interface, marketed as the Electronic Control Center (ECC), that included radio and climate control functions, date reminder, trip computer and user-configurable overspeed alarm, as well as diagnostic access to the vehicle's electronic systems and sensors. Later models were equipped with conventional push-button stereo and climate controls. The new system eliminated the trip computer functionality and the climate control buttons could access diagnostic information, replacing the diagnostic scanner capability formerly provided by the touchscreen. In 1990, the interior was redesigned, adding a driver's airbag and an optional CD player. In 1991, the "L27" 3800 engine and 4T60-E transmission replaced the "LN3" and hydraulic 4T60 units and the Reatta received a new ABS system, new 16" wheels, automatic headlamps and a cup holder built into the armrest. Each Reatta included a leather book containing the owner's manual and a pen. In 1990 and 1991, a zippered owner's folio was included holding the owner's manual, pen, flashlight and tire gauge, as well as a "Craftsman's Log" with the signatures of the supervisors for the car's assembly. In 1988, approximately fifty-five examples were designated "Select Sixties" and allocated to Buick's top sixty dealers. The models, internally designated model X22, featured a black exterior, tan interior, and unique "Select Sixty" hood emblems. In 1990, the Select Sixty program was repeated, with sixty-five white convertibles including special emblems, and a flame red interior with white bucket seats, white 16-inch wheels, and cup holder. Convertible After a delayed introduction due to design difficulties, Buick introduced the convertible Reatta in 1990 with a manually-operated top designed by ASC, available in vinyl or cloth with a glass rear window and electric defroster. When retracted, the top was protected by a rigid tonneau cover. The 1991 models featured power pull-down motors to assist in tightening the rear bow of the top to the tonneau cover. A Buick convertible would not be offered again until the four-seat Buick Cascada debuted in 2016. Production The first pilot car was finished at the Reatta Craft Centre in December 1986. Series production began in January 1988 and ended on May 10, 1991. The original car was sometimes referred to as a "1988½ model year", owing to its January introduction.
