    Buick Skylark — N-body (1992–1998)

    The Skylark was Buick's compact N-body car for the 1992 through 1998 model years; NICB lists the Custom and Limited four-door and the Custom and Gran Sport two-door for 1992, and the Skylark, Limited, Gran Sport and Custom for 1998. Every code here comes from GM's 1998 RPO code list for the Skylark, the only factory list in the archive for this car, so 1992 through 1997 have no code rows, and that list is word for word the Oldsmobile Achieva's and Pontiac Grand Am's: a code here may be a twin's equipment. LD9, L82 and K05 are also corroborated on the Chevrolet Malibu's 1998 order-guide page. Wikipedia's engine list for the Skylark shows the 2.3L L40 and LD2, the 2.4L LD9, the 3.1L L82 and the 3.3L LG7 and no 3.8L or 2.2L, so the 3.8L L36 and 2.2L LN2 that the shared list prints are not carried here; it also says 1998 was a fleet-only sedan year.
