Vehicle Overview
Little has changed for 2003 on Mercedes-Benz’s lower-priced, two-seat, retractable-hardtop convertible. A new, high-performance SLK32 AMG version emerged for the 2002 model year and is equipped with a 349-horsepower supercharged V-6 engine, racing-derived brakes and an AMG SpeedShift transmission. Only 1,000 models were destined for the U.S. market. A new Sport Package that is inspired by the SLK32 AMG is available for the regular SLK-Class models and includes a fresh front air dam, rocker panels and a rear valance.

Face-lifted for 2001, the SLK320 has a 215-hp, 3.2-liter V-6 engine, while the original SLK230 Kompressor uses a supercharged four-cylinder that makes 192 hp. Each model has Mercedes-Benz’s Electronic Stability Program.

Exterior
Equipped with sculpted rocker panels, Mercedes-Benz’s smallest model in the United States sits on a 94.5-inch wheelbase that is 5 inches longer than the Mazda MX-5 Miata’s. Push a button on the console and the articulating metal roof raises or retracts automatically into the dual-hinged trunk space in about 25 seconds. The trunk opens in two different modes: at the front to accept the roof or at the rear to fit a small amount of luggage. Door mirrors feature integrated turn-signal flashers.

The SLK32 AMG gets a special, recalibrated, reinforced suspension with unique spring rates and shock-absorber valving. Double-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, while a small lip spoiler at the rear of the trunk lid reduces aerodynamic lift by more than 50 percent, according to the manufacturer.

Interior
Two occupants get leather bucket seats. Standard equipment includes dual-zone air conditioning, an air filter, a leather-wrapped steering wheel and a Bose cassette stereo system. In addition to the V-6 engine and wood interior trim, the SLK320 has eight-way power seats and a telescoping steering wheel. Maximum cargo space is 9.5 cubic feet but is only 3.9 cubic feet with the top down.

Sport seats in the SLK32 AMG are upholstered in two-tone Nappa leather and come equipped with integrated headrests and what Mercedes-Benz calls “substantial” side bolsters. Two-tone leather trim throughout the interior mates with dark bird’s-eye maple wood. Mercedes-Benz’s Tele Aid emergency assistance system includes such functions as vehicle diagnostics, remote door unlocking and alarm monitoring.

Under the Hood
The hottest engine of the SLK-Class is the supercharged Kompressor V-6 in the SLK32 AMG, which whips out 349 hp and 332 pounds-feet of torque. The SpeedShift transmission in the SLK32 AMG promises shifts that are up to 35 percent faster than those in a conventional automatic. Mercedes-Benz claims the SLK32 AMG can race from zero to 60 mph in 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 the standard six-speed-manual transmission or with an optional five-speed-automatic unit that incorporates Touch Shift for manual gear changes.

Safety
Side-impact airbags, all-disc antilock brakes, traction control and an electronic stability system are standard in all models. A BabySmart child-recognition system keeps the front-passenger airbag from activating.

  • What a great little rekliable fun car

    Bought this used about 8 years ago and apart from minor faults seem to improve with age.I also have a V8 Jaguar but drive the Mercedes most of the time just for the fun. I live in a sunny climate and hardly ever have to close the roof. hard to believe this car is now 17 years old.

  • Love.

    After driving some serious junk, I finally had it and bought my 2003 SLK230 Kompressor with 75,000 miles. Solid German engineering. Performance and handling are perfect. Understated in all the right ways: purrs quietly but packs the power of a supercharger. Even the sound the doors make when they close screams attention to detail. Pretty sure if someone totaled it I would buy another one just like it. Cons: seats should never have left the factory without adjustable lumbar support (very disappointing). Leaking self-dimming mirrors should have been recalled. Few spots of rust on the roof that I didn't notice until after I bought the car, so make sure you look carefully.

  • The most underrated high performance car

    A pure joy driving experience, with beautiful lines. Hand built motor. Great handling. 0-60 in under 5 seconds. Fit and finish is very good. Older body style remains a classic.

  • Kompressor Kicks on all accounts

    No better value for your money on the MB SLK Kompressor! Even with a lot of mileage, if you maintain the maintenance aspect of the vehicle you will not be disappointed in it's performance. I've loved this car from the moment I drove it. Parting will be sweet sorrow.

  • 2003 MB SLK 230 Represents a Good Value

    I bought my '03 SLK in 2011 with 38,000 miles in near showroom condition, having obviously well cared for by its first owner. Compared to previous "big" SLs I owned, the SLK offers superior handling that reflects "soul," as if the car is exactly enjoying the drive, compared to earlier Series 1 and 2 SLs that were competent, and comfortable, but somewhat boring (though I loved the styling and the quality). The 4cyl engine is a tad rough and growls a bit compared to the available V6 3.2 liter (which I have in another Mercedes I own), but it does a good job, though the supercharger needed a new coupling to quiet a bit of noise it was making. A slightly more sporting exhaust would be welcome, and would camouflage the roughness IMO. The transmission shifts well, though until warm, it tends to shift at a slightly higher rpm that necessary. The 2 tone interior is very attractive, and the retractable hard top does it job of making the car superbly "all-weather" compared to cloth tops especially well. I routinely get 27mpg around town and 32mpg on the highway driving conservatively. Reliability has been flawless, though I don't put a lot of miles on it, reserving it for sunny day drives.

  • Too much fun!

    Bought an SLK 4 months ago, and it's been a so much fun to drive. It's our weekender car, and we have the top down 80% of the time. Handling is superb, and acceleration is great on the SLK320. I can't imagine what the SLK32 is like!

  • Very Fun, Reliable, and Safe Convertible

    A lot of fun and great in the sun. Very safe, as I've been hit by an SUV; a lot of damage to the car and not a scratch on me. Mercedes Benz builds incredibly safe cars, even the small ones like the SLKs

  • More GT ripper than Race-track Fiend

    SLK 32 is faster than the SLK 55 but not as feature-filled. Retractable hard-top is priceless. Fast when the transmission software work, needs reflashing almost annually however. No major mechanical problems after 4 years which weren't covered by warranty. Expensive tires which last about 1 year with aggressive driving. AMG parts are even more expensive than already expensive standard MB parts. Despite all that, you can't help but smile profusely while driving this precision machine. I don't think the handling is great enough to keep up with other "sports" cars, i.e. Z4 or Boxster on the track but, the engine pull/torque is fierce for such a small car and you can activate the save-your-bacon ESP with very little effort. I find the seats very comfortable but you'll have to try for yourself. Hands-Free phone is a must as you need both hands to drive this beastie safely. Rear-wheel drive is a must in a sports care and some throttle-steering is possible with this car but again it's not really made for the track. Not too bad in the snow with snow tires, and keep to level ground with reasonable snow accumulation. Traction control helps immensely. Do not underestimate this machine as a "chick-car" as many do with the older SLK's. In anyone's hands (male or female) this car goes very fast in a straight line and is a lot of fun to drive. I reccommend it highly for people that like to drive. So turn off the radio, drop the top, apply shades and try not to smile TOO much!

  • Nothing but fun !

    I bought this car used and it just gets better with time. The folding hardtop convertable as well as its sporty appearance makes this car a real head turner. Excellent handling & suspension makes driving a pleasure again! Other than an oil change, there has been no need to return the car for service. Worth the money !
