About This 2012 Mercedes-Benz SLK 350 Roadster
The 2012 SLK 350 sits at the top of the SLK lineup, and it shows. Finished in silver — a color that flatters every curve of this low-slung roadster — this two-door convertible has the kind of presence that turns heads whether the top is up or down. At just under 81,000 miles, this SLK is well within a range where a properly maintained Mercedes-Benz V6 has plenty of life remaining. For a sports car in this class, that mileage is completely reasonable and expected for a 2012 model year vehicle that has clearly been driven and enjoyed.
2012 Mercedes-Benz SLK 350 Performance and Engine
A V6 Built to Thrill on California Roads
Under the hood of this SLK 350 sits a 3.5-liter V6 engine producing 302 horsepower — a substantial upgrade over the base SLK 250's four-cylinder. Paired with Mercedes-Benz's sophisticated 7G-Tronic Plus 7-speed automatic transmission, power delivery is smooth, seamless, and genuinely exciting when you push into the throttle. The rear-wheel-drive layout gives the SLK 350 a classic sports car character — balanced, responsive, and engaging on everything from Pacific Coast Highway to the canyon roads east of Orange County.
The 7G-Tronic Plus transmission was one of the best automatic gearboxes in its class when introduced and continues to impress with its quick, confident shifts. Whether you're cruising up the 22 or winding through the hills above Anaheim, this drivetrain is calibrated for both comfort and sport.
Mercedes-Benz SLK 350 Features and Interior
Refinement You Can Feel
The SLK 350 trim brings a level of luxury and technology that sets it apart from lower configurations. The signature AIRSCARF neck-level heating system allows top-down driving even on cooler Southern California evenings — a genuinely clever Mercedes innovation. The retractable hardtop (VARIO-ROOF) means you get the rigidity and quiet of a coupe when closed and the freedom of a roadster when open, with no fabric top to worry about over time.
Inside, expect premium materials, supportive sport seats, dual-zone climate control, a COMAND infotainment system, and the kind of cabin fit-and-finish that defines the Mercedes-Benz ownership experience. For a vehicle in the $19,000 price range, the interior quality of the SLK 350 is difficult to match.
Mercedes-Benz SLK 350 Reliability and Ownership
What Owners and Experts Say About the 2012 SLK 350
The 2012 Mercedes-Benz SLK 350 earned strong reviews for its build quality, powertrain durability, and overall refinement. The M272 3.5-liter V6 engine has a solid track record for longevity when properly maintained, and the 7G-Tronic transmission is considered one of the smoother, more reliable units from this era of Mercedes-Benz engineering.
As with any used European luxury vehicle, staying current on service intervals — particularly oil changes, spark plugs, and transmission fluid — is the key to long-term reliability. Buyers who maintain this car as Mercedes-Benz recommends consistently report high satisfaction and low unexpected repair costs. At 80,906 miles, this SLK 350 is past the steepest part of its depreciation curve, which means you're getting a far better dollar-per-thrill ratio than buying new.

Yes — the 2012 SLK 350 is widely regarded as one of the best values in the used luxury roadster segment. It offers genuine Mercedes-Benz quality, a powerful V6 engine, and a stunning retractable hardtop design at a price point that has become very accessible in the used market. For Southern California buyers who want an open-air weekend car with real performance credentials, it's an excellent choice.
How many miles is too many for a used SLK 350?
For a well-maintained 2012 SLK 350 with a V6 engine, 80,000 to 100,000 miles is still very reasonable. Mercedes-Benz engines from this era routinely reach 150,000 to 200,000 miles with proper maintenance. At 80,906 miles, this vehicle has significant life remaining when serviced correctly.
What does the SLK 350 trim include over the SLK 250?
The SLK 350 upgrades to the 3.5-liter V6 engine producing 302 horsepower, compared to the SLK 250's turbocharged four-cylinder. It also typically includes additional sport and luxury appointments, upgraded wheels, and in many configurations, features like the AIRSCARF system and a sport-tuned suspension that elevate the driving experience significantly.
Does the SLK 350 have a manual or automatic transmission?
This particular SLK 350 is equipped with the 7G-Tronic Plus 7-speed automatic transmission — Mercedes-Benz's highly regarded dual-clutch-style automatic that offers both smooth everyday driving and crisp, quick shifts in sport mode. It can also be operated in manual mode via steering wheel paddles.
Is the retractable hardtop reliable on a used SLK?
Yes, the VARIO-ROOF retractable hardtop on the SLK is a well-engineered system with a strong reliability track record. Unlike fabric convertible tops, it doesn't degrade with age or UV exposure. The hydraulic mechanism should be inspected during a pre-purchase check, but issues are uncommon on well-maintained examples.
