The 2003 SL500 is a two-seat luxury roadster (convertible) with a retractable hardtop, allowing it to transform between a coupe and an open convertible in ~16 seconds. MotorTrend+2Cars.com+2
It was a clean-sheet redesign — the SL line had been in its previous form for about 12 years, so this generation introduced major updates. MotorTrend+1
Exterior styling draws on SL heritage (e.g. vents in the front fenders reminiscent of old SLs), while also reflecting contemporary Mercedes design cues, including aggressive wheel arches, smooth curves, xenon high-intensity headlights, and a sleek body shape with a low drag coefficient (~0.29) for that kind of car.

The interior is positioned as luxurious and high-quality: use of leather, fine wood or walnut trim, metal/aluminum accents, with craftsmanship and build quality emphasized. The cabin is meant to feel both sporty and refined. Cars.com+2MotorTrend+2
