    Chevrolet Beretta — L-body (1987–1996)

    The Heritage kits for 1988–1996 show the Beretta as a 2-door notchback coupe: the base coupe (1LV37), the GT (1LW37, the Z21 package) to 1993, the GTZ (1LZ37) for 1990–1993 and the Z26 for 1994–1996 (model 1LW37 in the order guides, 1LV37 with Z04 on the 1995 power teams page and the 1996 option-weight page), with a 1990 Indy pace car coupe and a convertible (1LV67) on the 1990–1991 power teams pages. Engines were the 2.0L LL8 and 2.8L LB6 (1988–1989), the 2.2L LM3 (1990–1991), the 3.1L LH0 (1990–1993), the 2.3L Quad 4 LG0 (1990–1994), the 2.2L LN2 (1992–1996) and the 3.1L L82 (1994–1996). Rows come from the kits' MVMA/AAMA specification pages (power teams, engine, chassis and convenience pages, and the optional-equipment weight pages) and from the order guides bound into the 1990 and 1994–1996 kits; there is no 1987 kit, so no code is claimed for 1987, although NICB's 1987 VIN manual lists the Beretta coupe. Paint and trim codes are listed for 1995–1996 only: the 1990 and 1994 order guides give two-digit color numbers and four-character trim combinations rather than RPO codes.
