The Buick Park Avenue was a full size luxury type vehicle produced by General Motors starting in 1975. However the Park Avenue was not originally a separate model. The Park Avenue was actually a trim level offered as part of the Buick Electra package. The Park Avenue name would not see its own model until the Electra was retired. 1991 was the first year that Buick offered this model separate from the Electra model. The first Park Avenue's utilized the C platform until 1997 and had a 3.8L 3800 series IV6 engine. The transmission on these early Park Avenues was the four speed 4T60-E automatic. It had a 110.8 inch wheelbase and the overall length of the car was 205.2 inches. The width was 74.9 inches and it had a height of 55.3 inches. By 1992, General Motors began using a supercharged engine that had exceptional acceleration given it's large size. In keeping with it's luxury billing, the Park Avenue had sleek silhouette reminiscent of a Jaguar. The hood had a large grille and the car had rounded lines and the taillights ran the full width of the car. These features were so popular with Park Avenue customers that General Motors eventually incorporated them into most of the automobiles in the Buick division. Although the largest car in the Buick lineup was the Roadmaster, the Park Avenue held the top spot for being Buick's most luxurious car. Unfortunately, as most of these things go, designers began to tinker with the body style of the Park Avenue and the next generation of this vehicle was not nearly as popular as the older model had been. The sleek style lines that had been so popular were replaced with boxier angles and many felt that the car had lost the elegant look of the earlier versions. Although not as popular as the earlier models had been, Buick left the body style largely untouched from 1997 until 2003 when minor cosmetic changes were made. The Park Avenue's final production year was 2007.
