2009 Mercedes-Benz SLK-Class Review

KBB Editors

By KBB Editors

Updated December 23, 2019

Our editors drive and evaluate hundreds of new cars every single year, turning thousands of miles and countless hours behind the wheel into helpful reviews, ratings, and comparisons. They also have lives outside of work, or so they think. You’d be surprised what you can learn by hauling a dirt bike, hunting for a wayward sippy cup, or just packing the trunk full of groceries.

Pros

If you love the idea of open-air driving but are concerned about the long-term reliability and security provided by a canvas soft-top, the 2009 Mercedes-Benz SLK might be the answer to your automotive dreams. The SLK’s retractable hardtop will last the life of the car, can’t be cut open and operates with just the touch of a button.

Cons

Tall folks may find legroom a little tight, especially on the passenger side where the firewall can cramp big shoes. Though the price is reasonable for the make, there are now much less expensive hardtop convertibles on the market, such as the Mazda MX-5 Miata and Volkswagen Eos.

What's New?

The SLK280 is replaced by the SLK300, which features the same engine but with a few more standard features. The SLK350 receives a bump in power to 300 horsepower and new 17-inch wheels. All SLK’s receive slight exterior changes as well as a new variable ratio Direct Steering System.

The 2009 Mercedes-Benz SLK is one of the more desirable premium roadsters, as it offers the advantages of both a hardtop coupe and an open-air convertible. Mercedes-Benz helped pioneer the retractable hardtop and the latest iteration operates with unwavering efficiency, capable of being raised or lowered in just 22 seconds. Beyond the SLK’s gorgeous exterior, stunning interior and enthusiast-inspired performance and handling capabilities, the car’s most attractive feature is its price. With a sticker starting around $45,000, the SLK is well within reach of luxury car buyers seeking a fun second vehicle for weekend getaways or romantic moonlight drives. A tiny trunk and minimal interior storage might limit how far you go and how much you take, but you’ll enjoy every minute of it.

2009 Mercedes-Benz SLK-Class Pricing

2009 Mercedes-Benz SLK-Class pricing starts at $8,480 for the SLK-Class SLK 300 Roadster 2D, which had a starting MSRP of $48,285 when new. The range-topping 2009 SLK-Class SLK 55 AMG Roadster 2D starts at $18,173 today, originally priced from $65,175.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2009 Mercedes-Benz SLK-Class models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the Mercedes-Benz SLK-Class

The SLK350’s 3.5-liter V6 makes 300 horsepower and can move the slick little roadster from zero to 60 miles per hour in less than six seconds. The experience is made all the more pleasurable by a quick-shifting six-speed manual transmission; the optional seven-speed automatic is equally as pleasing. The SLK feels more composed on the road than previous generations. Its ride has definitely been improved, with less harshness over bumps and improved stability in tight turns. You’ll find that the steering is precise but somewhat heavy, requiring authoritative input from the driver. With the top down, the AIRSCARF neck heater blows hard enough to take the chill out of the morning air, or the retractable hardtop can be locked in place, creating a cozy but quiet environment.

Interior Comfort

Mercedes has done a wonderful job of organizing the SLK’s interior without losing the look and feel common to all Mercedes products. The supportive bucket seats include the clever AIRSCARF option that blows warm air on the back of the neck, a nice feature to have when cruising on crisp autumn mornings. The SLK’s retractable hardtop still eats up trunk space, but the design responsibly leaves some usable room for storing small luggage and valuables.

Exterior Styling

It’s amazing what a few extra inches can do for a car. Compared to the first-generation SLK, the 2009 model feels downright spacious. The SLK’s wide footprint gives it a low and athletic stance, and its SLR McLaren-like front end turns heads at every encounter. The perfectly aligned side bodylines appear as though carved from a single block of steel, with a gently-curved rear end that features flush-mounted cut-in tail lights and twin trapezoidal exhaust ports. The SLK looks as good with its retractable hardtop in place as it does when that top is tucked away beneath the color-matched hard cover.

Favorite Features

AIRSCARF
The AIRSCARF seat heating system blows warm air on the back of your neck and shoulders, keeping you warm when the air outside isn’t.

Improved Clear Coat Paint
Improved Clear Coat paint is 40 percent more durable, helping to resist small scratching that appears after repeated washing and waxing.

Standard Features

The SLK comes standard with a six-speed manual transmission, four-wheel anti-lock disc brakes (ABS), traction control, slip control, stability control, dual-zone automatic air conditioning, front and rear fog lights, dual-heated power mirrors, AM/FM stereo with six-disc CD changer, dual front knee and side-impact airbags, leather seats, cruise control, leather-wrapped tilt/telescopic steering wheel and 17-inch alloy wheels.

Factory Options

Options include a seven-speed automatic with manual-shift mode, dual eight-way power seats with memory, heated seats, harman/kardon audio, navigation, HID headlamps and several different designo designer trim packages.

Engine & Transmission

The 2009 Mercedes-Benz SLK300 has a 228-horsepower V6 that feels plenty peppy, but not rocket-ship fast. If you can swing the extra cash, the SLK350 is the way to go. If money is no object, you don’t mind a harsher ride and you want the most in performance, the SLK55 AMG is sure to please.
