In the 1950s the nomenclature changed again, and trim levels also received names that were then mated with the model numbers. This resulted in the Oldsmobile 88 emerging as base Dynamic 88 and the highline Super 88. Other full-size model names included the "Holiday" used on hardtops, and "Fiesta" used on its station wagons. When the 88 was retired in 1999 (with a Fiftieth Anniversary Edition), its length of service was the longest model name used on American cars after the Chrysler New Yorker. Mid-1955 also saw the introduction of the four-door Holiday pillarless hardtop, the industry's first (along with Buick). General Motors' styling as a whole lost its frontrunner status in 1957 when Chrysler introduced Virgil Exner's "forward look" designs. When compared side to side, Oldsmobile looked dated next to its price-point competitor DeSoto. Compounding the problem for Oldsmobile and Buick was a styling mistake which GM called the "Strato Roof". Both makes had models which contained the heavily framed rear window, but Detroit had been working with large curved backlights for almost a decade. Consumers disliked the roof and its blind spots, forcing GM to rush a redesign into production on some of its models. Oldsmobile's only off year in the 1950s was 1958. The nation was beginning to feel the results of its first significant post war recession, and US automobile sales were down for the model year. Oldsmobile, Buick and Cadillac received a heavy-handed makeover of the 1957 GM designs. The Oldsmobile that emerged in 1958 bore little resemblance to the design of its forerunners; instead the car emerged as a large, overdecorated "chromemobile" which many felt had overly ostentatious styling. Up front, all 1958 Oldsmobiles received one of General Motors' heavily styled front fascias and quad-headlights. Streaking back from the edge of the headlights was a broad belt consisting of two strips of chrome on regular 88s, three strips on Super 88s, and three strips (top and bottom thin, inside thick) on 98s that ended in a point at mid-body. The bottom of the rear fender featured a thick stamping of a half tube that pointed forward, atop which was a chrome assembly of four horizontal chrome speed-lines that terminated into a vertical bar. The tail of the car featured massive vertical chrome taillight housings.
