How Does the 2011 Mercedes-Benz SLK-Class Compare to Other Convertible?
Regarding features, the SLK-Class offers a retractable hardtop, a feature that provides coupe-like security and weather protection, setting it apart from the soft-top Z4 and Boxster. The Audi TT offers similar features but in a more compact package. In terms of reliability, the SLK-Class can be prone to some issues, as mentioned previously, but with proper maintenance can be reliable. The Porsche Boxster generally has a better reliability record.
Price-wise, the SLK-Class typically falls between the Audi TT and Porsche Boxster. As used cars, a 2011 SLK represents good value, but potential buyers should factor in higher maintenance costs.
Alternatives to consider include the BMW Z4 for its sporty handling, the Audi TT for its stylish design and available quattro all-wheel drive, and the Porsche Boxster for its superior driving dynamics. If performance and handling are top priorities, the Boxster is a better choice. If a retractable hardtop is essential, the SLK-Class remains a strong contender.

One of a kind !!! LOW,LOW milage !!!Great car, we just don't drive it enough. Bought it for my wife and we have two other vehicles that we drive most of the time.

owned 2 back to back, oil changes only, great car=Hard top convertible, well engineered, reliable, stylish, comfortable and a trunk big enough for a full set of golf clubs

Love my SLKThis car is fun and sporty and purrs like a kitten. The breaks and steering are very precise. The car is easy to park but because the front is so low watch out for the curb. The front defroster, elecgtric tilt steering wheel and rear speaker performance are all disapointing . The convertable hardtop disappears like magic. Remember to close the interior shell in the trunk or the top will not close. I keep the running lights on to not get cut off in traffic. Washing the car is snap because of it's compact size. Previously I drove a 2008 GMC pick up and the insurance premium was $60 more for 6 months than the SLK.

SLK300 = Miles of smiles!I have wanted one of these ever since they came out in 1998... So I asked the guy above and saved my money and waited. Bought the car in January 2011 and drove it home, and have not regretted it. the car is solid, safe, fast as I need. This vehicle gets 23-28 in town (18-24 on snow) and 30-34 mpg at 65 with the a/c on arctic on the highway. The performance is fast and sophisticated - if you want a sledgehammer buy the SLK55 AMG! This car is comfortable - I'm 6' 2" and it is adjustable down to anyone smaller. The interior is in my opinion better laid out, roomier and more comfortable than the SL's. The 2011 is the best of the second generation series W172's in styling inside and out. This car feels SOLID and safe. You ride in the car not on it. SLK's are not cheap even with a lease, but I can't think of any car I would trade you mine for at four times the price. This car is a daily driver I have driven it in all kinds of weather, from snow to sweltering and my SLK has never let me down or left me stranded. (Some advice if you drive year round- if you live where it snows get the best SNOW tires you can, and anticipate where you are going and how to get there and you can do just fine, but be warned SLKs are no 4matic ML or G-Wagon. My SLK is the best present I have ever given myself! Thanks Big Guy in the sky for the blessing!
