At the beginning of the '90s, Buick introduced a new lineup in its stable with the Park Avenue and Park Avenue Ultra models. The model was a new contender in the premium car market. The Park Avenue had some design cues inspired by older Jaguar models. The front grille, the rounded lines, and the belt line were inspired by the Jaguar XJ line. The car maker insisted that the car was in the same league with the Jaguar XJ, Mercedes-Benz E 300 and the BMW 535i from that era, but the Park Avenue was considerably cheaper. Due to its big size, the Park Avenue range featured a long wheelbase of 2.81 m (110.8”) that offered a sleek, elegant look for the vehicle. The rounded front and rear end and the curved roof line were some features that allowed a low drag coefficient. Inside, the Park Avenue offered a luxurious interior, with leather seats and wood. It featured a dual-zone climate control, which was not that common in 1991. There were few buttons on the steering wheel. There was power everything, starting with the windows, the seats, and the sunroof. Since the car was front-wheel-drive and featured a big wheelbase, it offered plenty of room for the rear passengers. Under the hood, there was the most important difference between the Park Avenue and the Ultra version. Both cars were fitted with a 3.8-liter V6, but only the Ultra featured a supercharger and it offered 40 more horsepower than the 200 hp, regular, Park Avenue. The standard transmission for both was a 4-speed automatic with overdrive.
