The 2003 BMW 5 Series represents the fourth generation (E39) of this renowned German sedan. It is known for its blend of performance, luxury, and style. Engine options span from the 225-hp 2.5-liter Inline-6 in the entry-level 525i, to the responsive 290-hp 3.5-liter Inline-6 in the 535i, and up to the spirited 394-hp 5.0-liter V8 in the M5 model. All engines marry to a precise 6-speed manual or 5-speed automatic transmission with RWD. The 5 Series offers a rich array of safety features, including stability control, ABS, and multiple airbags. Inside, the BMW 5 Series impresses with an upscale cabin appointed with features such as a premium sound system, optional navigation, and automatic climate control. While there were no major changes for 2003, it stands as the last year of the acclaimed E39 generation, making it a significant model in BMW's lineage.
