2004 Mercedes-Benz SLK-Class Overview

By Cars.com Editors
Vehicle Overview
A Special Edition of Mercedes-Benz’s lower-priced retractable-hardtop convertible has joined the lineup for 2004. Equipped with polished 17-inch wheels, the Special Edition SLK-Class roadster features a painted grille, a rear spoiler, special sport seats and Nappa leather-covered roll bars.

A high-performance SLK32 AMG version contains a 349-horsepower supercharged V-6 engine, racing-derived brakes and AMG’s SpeedShift five-speed-automatic transmission. A Sport Package inspired by the SLK32 AMG is available for regular SLK-Class models. Redesigned SLK-Class models arrive in the 2005 model year.


Exterior
Mercedes-Benz’s smallest sports car features sculpted rocker panels and sits on a 94.5-inch wheelbase — that’s 5 inches longer than the Mazda Miata’s. Push a button and the articulating metal roof rises or retracts automatically in about 25 seconds. The trunk opens at the front to accept the roof or at the rear to reveal a small luggage compartment. The door mirrors feature integrated turn-signal flashers.

The SLK32 AMG gets a recalibrated, reinforced suspension with unique spring rates and shock-absorber valving. Twin-five-spoke, 17-inch alloy wheels on the SLK32 AMG hold P225/45ZR17 tires up front and P245/40ZR17 tires in the rear. A front air dam incorporates AMG fog lights.


Interior
Two occupants get leather bucket seats. Standard equipment includes dual-zone air conditioning, an interior air filter, a leather-wrapped steering ...

Interior
Two occupants get leather bucket seats. Standard equipment includes dual-zone air conditioning, an interior air filter, a leather-wrapped steering wheel and a Bose cassette stereo. In addition to wood trim, the SLK320 has eight-way power seats and a telescoping steering wheel. Maximum cargo space is 9.5 cubic feet, but that space shrinks to 3.9 cubic feet when the top is down.

Sport seats in the SLK32 AMG are upholstered in Nappa leather and feature integrated headrests and what Mercedes-Benz calls “substantial” side bolsters. Leather trim and dark bird’s-eye maple are used.


Under the Hood
The hottest engine in the SLK-Class lineup is the supercharged 3.2-liter V-6 in the SLK32 AMG, which whips up 349 hp and 332 pounds-feet of torque. Mercedes-Benz claims the AMG SpeedShift five-speed-automatic transmission produces shifts that are up to 35 percent faster than those of a conventional automatic. Mercedes-Benz claims a 0-to-60-mph acceleration time of 4.8 seconds.

The supercharged 2.3-liter four-cylinder engine in the SLK230 Kompressor roadster is rated at 192 hp. Moving up to the SLK320 brings a 215-hp, 3.2-liter V-6. Both engines can team with a six-speed-manual gearbox or an optional five-speed automatic that incorporates TouchShift manual gear selection.


Safety
Side-impact airbags, all-disc antilock brakes, traction control and an Electronic Stability Program are standard. A BabySmart child seat-recognition system prevents the front-passenger airbag from deploying when a known child-safety seat is installed.

Driving Impressions
The SLK is agile and nimble and maneuvers like a traditional small sports car. With the 2.3-liter engine and an automatic transmission, acceleration is rather energetic, though well short of the big Benzes, and there’s little evidence of the supercharger’s operation. The SLK is a little less solid and a bit bouncier on the road than its larger cousins — but not by much. Space is quite plentiful for two people.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
