Base models have a leaner equipment list, but as of last year, the Mercedes-Benz SLK-Class has seen its standard-features list upgraded to include Bluetooth and a premium audio system. Leather upholstery, an in-dash CD changer, and cruise control also are standard. ConsumerGuide adds the SLK roadsters include "air conditioning w/dual-zone automatic climate controls" and a "leather-wrapped steering wheel w/radio controls," along with "height-adjustable bucket seats" and a "six-disc CD changer." Edmunds reports "a premium audio system with a five-inch LCD screen" is also standard on all three versions of the 2010 SLK, while J.D. Power notes the audio system "includes [a] hands-free phone link."
The 2010 SLK-Class options list is extensive, including a SmartKey system that allows raising or lowering the top remotely, a Harman Kardon sound system, a navigation system, the latest version of the company's COMAND screen-based interface, bi-xenon headlamps, dual-zone climate control, and an attractive burl walnut trim. An iPod interface is newly available, and the optional sound system comes with an SD memory card slot, as well as HD and satellite radio. Kelley Blue Book notes other options include "dual eight-way power seats with memory" and "heated seats." The optional Multimedia Package includes a "navigation system w/voice recognition," ConsumerGuide observes, and the "COMAND control screen," along with an upgraded "Harman/kardon sound system" and "hard drive." Other minor options on the Mercedes-Benz 2010 SLK-Class roadster include "HID headlamps and several different designo designer trim packages," according to Kelley Blue Book.
The single best feature available on the 2010 Mercedes-Benz SLK that's not offered on a rival vehicle in its class is AIRSCARF, which gently blows hot air around your neck from behind the headrest area, making cold, sunny days so much more enjoyable with the top down. Edmunds explains it "channels warm air to your neck and shoulders via dedicated ducts in the headrests" and "makes the SLK a true four-season convertible."
