2003 Mercedes-Benz SLK-Class Review

Lots of fun in this roadster with lots of options and safety features.

Reviewed by Automotive on


The Mercedes-Benz SLK-Class was originally offered in the 1990s as an answer to the various European roadster convertible options available. It was the first to offer a solid metal retractable roof in place of the conventional fabric top. The system was well designed and works easily. The powertrains of the SLK-Class were also designed for fun and function. With either engine choice, the SLK does a great job showing off its power and creating a challenging driving experience for the driver. Finding a 2003 model in good condition would make this car a good choice for anyone looking for a well running, impressive convertible.

What's New

The 2003 Mercedes-Benz SLK-Class makes no significant changes.


The 2003 Mercedes-Benz SLK-Class has a focus on style and design with an emphasis on performance. The body style of the roadster is intended to attract attention, and it certainly does. It offers a sleek, modern design with a slightly rounded front end and grille. The Mercedes-Benz badge is prominently featured in the center of the grille. The SLK-Class rides around on 16-inch alloy wheels and has a power retractable hard top roof. This year’s SLK-Class is available in a variety of colors. Some of the more popular choices included Sapphire Blue Metallic, black, and Magma Red.


The 2003 Mercedes-Benz SLK-Class is designed to be as comfortable and luxurious as possible in the cabin. Even the lower trim levels are equipped with leather bucket seats and power accessories. Cup holders and interior storage space, thanks to the center console, are handy features as well. Cruise control and air-conditioning are standard features, too. Alloy trim is found on the dash, doors, and center console. Leather makes an appearance on the steering wheel and shift knob.

The upper trim levels are comfortable and well equipped as well. The seats are leather sport seats and offer the ability to adjust the height as well as a multi level heating system in both seats. Alloy and leather decorate the doors, dash, and center console, while leather alone is the primary material for the steering wheel and shift knob. Six Bose speakers are attached to the car’s standard stereo system.

Performance & Handling

The 2003 Mercedes-Benz SLK-Class is designed for fun and performance, and it works hard to meet the expectations. It is available with two engine choices: the 2.3-liter four-cylinder and the 3.2-liter V-6. Both engines adequately power the roadster and can be counted on for a smooth and quiet ride on the highway. Naturally, really serious drivers are sure to find the V-6 option more of a challenge, even without the benefit of a manual gearbox to help things along.


The 2003 Mercedes-Benz SLK-Class is equipped with four-wheel anti-lock brakes with front and rear ventilated discs are standard along with emergency braking assist. Dual front side mounted airbags are included as well. Stability and traction control are important features for this car in addition to the electronic brake force distribution system. Front integrated headrests are in place to provide additional protection for the head and neck in the event of an accident. The seatbelts are pre-tensioning as well.
