When the rear seats are folded down, this capacity increases to 339 liters (12 cubic feet), providing extra storage flexibility.

Typical single-car garages measure around 2400 mm to 3000 mm (94 to 118 inches) in width. The SL’s width is 1820 mm (71.7 inches) without mirrors and 2069 mm (81.4 inches) with mirrors opened. Because the width with mirrors is a critical factor, owners should confirm garage width to ensure enough space for mirror clearance when parking. Height and length are well within standard garage limits.

The 2008 facelifted Mercedes-Benz SL R230 saw modest changes in styling and equipment but retained very similar fundamental dimensions compared to the original R230 produced from 2001 to 2008. Both models shared a length close to 4560 mm (179.5 inches), width around 1820 mm (71.7 inches), and height near 1317 mm (51.9 inches). The facelift primarily targeted cosmetic and mechanical upgrades rather than significant size changes, maintaining the same sporty and luxurious roadster proportions.

Compared to competitors in the luxury roadster segment such as the BMW Z8, Audi R8 Spyder, or the Jaguar XK, the Mercedes-Benz SL R230 facelift offers a balanced size that aligns well with peer vehicles. For example, the SL is longer and slightly wider than the BMW Z8 but with more usable luggage space. It tends to be bulkier than the Audi R8 Spyder, which focuses more on sportiness, but offers comparable road presence. The SL’s combination of length (4562 mm), width (1820 mm), and height (1317 mm) positions it as a well-sized and comfortable grand touring roadster.

The Mercedes-Benz SL R230 facelift came equipped with a variety of tire and rim size options to enhance both performance and aesthetics. The rim sizes range from 17 to 19 inches in diameter, including sizes like 9.5J x 18, 8.5J x 18, 8.5J x 17, 9.5J x 19, and 8.5J x 19. Corresponding tire sizes include 285/35 R18, 255/40 R18, 255/45 R17, 285/30 R19, and 255/35 R19. These options allowed drivers to customize their vehicle’s handling dynamics and visual appeal while preserving ride comfort.

The permitted roof load capacity for the Mercedes-Benz SL R230 facelift (2008-2011) is 75 kg (165 pounds). This rating reflects the maximum weight that can be safely placed on the vehicle’s retractable hardtop roof when it is closed, such as a roof box or luggage rack. While the SL's retractable roof is a complex mechanism, the relatively modest roof load capacity emphasizes safety and structural integrity, making it suitable for light loading but not heavy cargo on the roof.

Yes, curb weight discrepancies across different trims and engine options are typical for the Mercedes-Benz SL R230 facelift. Models range from approximately 1740 kg (3836 pounds) to 2045 kg (4508 pounds) depending on features such as engine size, additional safety or luxury packages, and drivetrain configurations. Higher-performance AMG variants or those equipped with all-wheel drive generally fall toward the heavier end of the spectrum due to additional reinforcements, turbocharging components, and equipment.

Key highlights include a fully retractable hardtop roof that transforms the car from coupe to roadster, sophisticated drivetrain options including powerful V8 and V12 engines, and enhanced safety features introduced in the facelift such as improved adaptive lighting and stability controls. Its dimensions provide a balanced and agile footprint, while interior refinements emphasize comfort and state-of-the-art electronics, solidifying the SL's status as a pillar in the luxury roadster market.
