The late 1990s witnessed a surge in the popularity of compact convertible sports cars, with models like the Mazda MX-5, MGF, and BMW Z3 capturing the hearts of driving enthusiasts. Mercedes-Benz, not wanting to miss out on this burgeoning market, introduced their contender: the R170 SLK, an acronym for ‘Sportlich Leicht Kurz’ – Sporty Lightweight Short. While the name might lack a certain flair, it accurately reflects the car’s initial concept. Built upon a scaled-down C-Class platform, the SLK boasted a weight ranging from approximately 1200kg to 1460kg, depending on specification, and offered a selection of engines hinting at a sporty character. But did the Mercedes SLK 320, the V6 variant, truly live up to the “sporty” part of its name, or did it carve its own niche? Let’s delve into a comprehensive review of the Mercedes SLK 320 to uncover its strengths and weaknesses in today’s market.
The SLK 320, positioned as the top-tier model in the initial SLK range, features a 3.2-liter naturally aspirated V6 engine. While slightly heavier than its four-cylinder counterparts, this engine compensates with a claimed output of 215 horsepower. To put this into perspective, the base SLK 200 generated a modest 134 horsepower. The supercharged SLK 200 Kompressor and SLK 230 Kompressor variants offered a step up in performance, producing between 160bhp and 195bhp, yet still falling short of the V6’s power. Early models up to 2001 were paired with a five-speed manual gearbox, while later versions received a six-speed manual. However, the model under review, the SLK 320, is equipped with Mercedes’ 5G-Tronic automatic transmission. And in reality, this automatic gearbox arguably complements the SLK 320’s overall character most effectively.
For those seeking a raw, driver-focused experience akin to a Mazda MX-5, the Mercedes SLK 320 might present a slightly different proposition. Even with the V6 engine at its disposal, the SLK 320 doesn’t deliver an immediate surge of power unless you firmly depress the accelerator pedal. This slight hesitation can be partly attributed to the automatic transmission, which isn’t always eager to execute rapid downshifts. However, even in a manual version, the SLK 320’s power delivery is unlikely to match the energetic feel of an Audi TT from the same era.
In terms of handling, the SLK 320 offers a respectable level of grip when navigating corners. Yet, it provides limited feedback through the steering wheel, lacking the communicative nature desired by true sports car purists. For enthusiasts adamant about extracting maximum sportiness from an SLK, the rare AMG variant presents a high-performance alternative. The SLK 32 AMG utilizes the same M112 V6 engine block as the standard SLK 320, but crucially, it benefits from a twin-screw supercharger.
This forced induction system elevates the power output to an impressive 349 horsepower, significantly reducing the 0-60mph sprint time from 6.9 to a brisk 5.2 seconds. Despite these impressive figures, the SLK 32 AMG still shares the same chassis as the regular SLK, which some might perceive as lacking ultimate sporting finesse. Therefore, if a truly sporty German convertible is your priority, a Porsche Boxster, or a more budget-friendly Audi TT, could be more aligned with your aspirations.
However, shifting focus from outright sportiness reveals the Mercedes SLK 320’s true strengths and its intended purpose. More than a sports car in the traditional sense, the SLK 320 excels as a comfortable and stylish convertible cruiser, ideally suited for enjoying sunny days. And in this role, it performs admirably.
A key attribute for any convertible is its roof mechanism, and the SLK’s retractable hardtop is arguably its most significant selling point. The hydraulic system allows for effortless operation – simply press a button, and the metal roof elegantly folds away, transforming the coupe into an open-top roadster. Furthermore, Mercedes pioneered the retractable hardtop in this segment, differentiating themselves from Porsche, BMW, and Audi, who were still employing fabric roofs at the time.
The hardtop offers practical advantages beyond mere novelty. It provides enhanced security, reduced wind noise, and superior leak resistance compared to traditional soft tops. However, it’s not without drawbacks. The hardtop mechanism adds weight, further reinforcing the SLK’s bias towards comfort over outright agility. Aesthetically, the hardtop design is also a point of contention, with opinions varying on its visual appeal.
The overall styling of the SLK is understated. While some might describe it as subtly elegant, others might find it bordering on bland. The most prominent design element is arguably the iconic three-pointed star emblem on the grille. The mere presence of a Mercedes-Benz badge and the allure of a two-door convertible often suffice to satisfy buyers seeking a certain image, as the design details themselves are not particularly striking.
Stepping inside, the interior of the SLK 320 genuinely embodies the essence of a luxury roadster. The wooden trim on the dashboard exudes a sense of sophistication, although the accompanying switchgear hints at the car’s age. Nevertheless, the controls are logically arranged and within easy reach, contributing to a well-designed cabin environment. Comfort is also a priority. The leather upholstery is plush, and the driving position provides a good view of the road and instruments. Taller drivers might find the seating position slightly restrictive, potentially needing to recline the seat more than usual to feel fully comfortable.
A minor ergonomic quirk within the SLK’s interior is the traditional Mercedes placement of all stalk-mounted driver controls on the left side of the steering column. This arrangement can lead to occasional confusion, particularly with the cruise control stalk positioned directly above the indicator stalk, resulting in accidental cruise control activation when intending to signal. However, this is a matter of familiarization and muscle memory adaptation.
On the road, the SLK 320 delivers a refined and comfortable cruising experience. The suspension tuning reflects the car’s overall character, prioritizing ride comfort over sharp handling. It effectively absorbs road imperfections, prioritizing passenger comfort rather than transmitting every road detail to the driver.
Similarly, while the 3.2-liter V6 engine might not offer exhilarating performance, it provides ample power for relaxed cruising and confident overtaking. It’s a smooth and refined engine that complements the SLK’s comfortable nature. However, it’s worth noting that the smaller-engined SLK 200, particularly the early non-supercharged versions, might feel somewhat underpowered, especially for a car marketed as a “sports car”.
Ultimately, the Mercedes SLK 320’s appeal lies in its nuanced character. If your priority is a two-seater convertible with genuine sports car credentials, the SLK 320 might not be the ideal choice. However, if you seek a well-priced, comfort-oriented drop-top with a touch of Mercedes-Benz prestige, it presents a compelling option. In the current used car market, entry-level four-cylinder SLK models can be found for under £1000, while even well-maintained V6 examples rarely exceed £6000.
Depending on the engine and condition, a good example of the Mercedes SLK can be acquired for between £2500 and £5000 – a reasonable price for a stylish and comfortable convertible bearing the Mercedes-Benz star. For those prioritizing open-top cruising and refined comfort over outright sportiness, the Mercedes SLK 320 offers a compelling blend of luxury and value in the used car market.
