    Chevrolet Monte Carlo — fifth generation, W-body (1995–1999)

    The fifth-generation Monte Carlo was a two-door coupe on GM's W-body, sold as the LS and the Z34 and assembled at Oshawa, Ontario (Wikipedia). Its 1998 and 1999 rows come from GM's RPO code lists for those years, which are word for word the Chevrolet Lumina's lists, so some codes may be the Lumina sedan's equipment; the 1995–1997 rows come from the Heritage kits (order-guide option and color pages, and weight sheets, with 1996 shown by weight sheets only). The engines are the 3.1 L L82 (1995–1999; 1996 from the 1996 kit p.8), the 3.4 L LQ1 (1995–1997, Z34) and the 3.8 L L36 (1998–1999), with the 4T60-E and 4T65-E automatics; codes shared with the Grand Prix, Regal, Century and Intrigue W-body docs follow those docs' wording.
