About the Mercedes-Benz SLK300

Vehicle Summary

Indulge in a sporty and luxurious roadster with the Mercedes-Benz SLK300, which was released as the base model of the SLK-Class and produced through 2016. This small-yet-mighty roadster features a power-retractable convertible top, letting you feel the wind through your hair as you blaze your own trail. 

On the SLK-Class' second generation (2005-2011), the rear-wheel-drive SLK300 model is equipped with a zesty 3.0L V6 engine at 228 hp. Looking for even more excitement behind the wheel? The third-generation SLK300 is powered by a turbocharged 2.0L four-cylinder engine at an impressive 241 hp.

No matter which generation of SLK300 you lean towards, you'll enjoy such standard equipment as a power-retractable convertible top, robust sound system, and Bluetooth® connectivity for easy hands-free calling and control of your music. From a space standpoint, every SLK300 offers 10.1 cubic feet of cargo space behind its seats (with roof up), which is great for storing a couple of duffel bags for a weekend road trip. If you're shopping for a sporty roadster to power your adventures, a used Mercedes SLK300 is definitely worth a look.

Reviews for Mercedes-Benz SLK300

Overall Rating

4.6 out of 5(11 reviews)

Pure Exhilaration!

Two words that most aptly describe this car: pure exhilaration! I've owned over thirty cars and my 2010 Mercedes-Benz SLK 300 beats them all hands down. The interior appears cramped at first outward glance, but the body-contouring seat fits my 5'10" frame perfectly. This six-cylinder car has impressive rapid acceleration capabilities and hugs the road as if it were on rails. The convertible top is truly a feat of German engineering at its finest. The Formula One inspired front nose is beautiful and slices through the wind with the gentlest of ease. I purchased this as a pre-owned vehicle as I do not care for the front nose of the 2012 and 2013 SLK models, which appears more like those on today's many newly domestic-made automobiles. The six-CD/DVD navigation system, integrated Bluetooth phone capabilities, and voice command prompts add bells and whistles to the car's numerous bells and whistles. As I've stated at the beginning of this review, this car is pure exhilaration!

Sexy Sophisticated

This is a super fun car to drive. I have always wanted a smaller car that you can park with out a problem. I love everything about it. The Con's would be it is small for a tall person over 6ft other then that this car rocks.

SLK Roadster

I bought the same car up in Boston, MA., with only 32K miles on it. It is fully loaded, but without the nav system, for the same price. The only negative I have is that, with any coup, the doors open wide. So, getting in and out in a cramped parking lot is a pain. To get into the car easily, you need to be able to open the door fully. Other than that you are squeezing into it. The ride is like most sports vehichles. It hugs the turns, grips the road, but has a bumpy suspension. Like BMW says, you're not buying a luxury sedan you are buying a sports car. I did take it out on an empty stretch of straight highway and got it up to 120 mph without any trouble at all, and VERY quickly. The car drove incredibly well at that speed, and had plenty of room to peg the needle if I hadn't been worried about running into a "Statie". Maybe one day I will take it to Charlotte/Concord Speedway and see what it can really do.
