The 2003 Chrysler 300M, LHS, Concorde, and Intrepid are a quartet of full-size sedans that represent a pivotal moment in Chrysler's history. These cars, underpinned by the Chrysler LH platform, departed from the brand's traditional, boxy styling, embracing a more modern and aerodynamic design language. While sharing a common platform, each model offered distinct visual identities. The 300M, with its sleek lines and sporty character, targeted younger buyers. The LHS, boasting a more luxurious and refined aesthetic, appealed to a mature demographic. The Concorde, characterized by its smooth curves and understated elegance, served as the flagship model, while the Intrepid, with its angular lines and pronounced grille, offered a more value-oriented option. Beyond their aesthetic differences, these vehicles also featured various powertrain options, including V6 and V8 engines. While all models shared a well-equipped interior with comfortable seating and ample cargo space, specific features and technology varied between trims. These sedans were praised for their comfortable ride, spacious cabin, and engaging driving dynamics, particularly the 300M which benefitted from its sport-tuned suspension. However, they faced competition from other domestic and foreign manufacturers who offered similar features and performance at comparable price points. While no longer in production, the 2003 Chrysler LH-platform sedans remain a significant chapter in the brand's history, representing a period of modernization and diversification that helped define the Chrysler of the early 2000s.
