Mercedes-Benz, despite enjoying sales growth in the preceding years, identified a significant void in their vehicle lineup that had persisted since 1993. This gap stemmed from their absence in the all-wheel-drive (AWD) market since the discontinuation of their 4Matic sedans and wagons after the 1993 model year. This left them exposed to competition from brands like Audi, Subaru, and Volvo who were capitalizing on the growing AWD demand. Recognizing this vulnerability, Mercedes-Benz first reintroduced AWD to their E-Class sedans and wagons and then, in 1997, launched the ML320 sport-utility vehicle into the market. Further expanding their SUV offerings, Mercedes introduced the more powerful ML430 for the model year this review is based on.
The 1999 Mercedes-Benz ML320 was meticulously engineered as a distinctive Mercedes, designed to confidently handle both off-road terrains and adverse weather conditions. Crucially, it achieved this without compromising on the hallmarks Mercedes-Benz clientele had come to expect: luxury, safety, and performance. For the 1999 model year, the ML320 enhanced its standard equipment list to include the Electronic Stability Program (ESP), Brake Assist, BabySmart child seat recognition system, and the Homelink programmable garage door opener. Remarkably, these enhancements were introduced with only a modest $1,000 increase to the Manufacturer’s Suggested Retail Price (MSRP).
Building upon the foundation of the ML320, the ML430 represented a step up in the range, commanding an additional $10,000. This premium brought with it a more refined and luxurious interior ambiance, along with the enhanced performance of a V8 engine. Beyond the standard features shared with the ML320, the ML430 boasted standard leather-trimmed seating, elegant burl walnut interior trim, heated eight-way power-adjustable front seats, an automatically dimming rearview mirror, a lockable safety box for valuables, a trip computer, and privacy glass. The exterior of the ML430 was also distinguished by a unique design incorporating body-colored bumpers, rocker panels, rub strips, and rearview mirror housings. It further featured wider 275/55R17 tires mounted on stylish seven-spoke, 17-inch alloy wheels.
These Mercedes-Benz SUVs ingeniously merged technologies traditionally found exclusively in either cars or trucks. Utilizing a robust frame boxed at both ends, the M-Class achieved a level of torsional rigidity typically associated with serious off-road vehicles. To this truck-like frame, Mercedes expertly integrated a four-wheel independent double-wishbone suspension system. This combination resulted in an exceptional on-road driving experience, allowing the ML320 and ML430 to navigate slalom courses with speeds comparable to the E320 sedan. While the off-road capability of the ML-Class was certainly competent for most needs, it was acknowledged that pitting these vehicles against dedicated off-road specialists like the Land Rover Discovery might reveal limitations in truly demanding off-road situations.
Reflecting its Mercedes-Benz lineage, the interior of the ML-Class SUVs exhibited the sophisticated touches expected of vehicles bearing the three-pointed star. Interior materials were of high quality throughout, with the exception of the dashboard plastic. The seats provided ample comfort for extended drives, and practical features included multiple cupholders for both front and rear occupants. The audio system delivered excellent sound quality, and the secondary controls were designed with improved clarity, avoiding the confusing pictograms that had sometimes characterized previous Mercedes-Benz models.
When contrasted with competitors such as the GMC Yukon Denali and Jeep Grand Cherokee Limited, the Mercedes-Benz M-Class emerged as the superior choice for the majority of driving scenarios, with the exception of the most extreme off-road challenges. On paved roads, the on-road refinement and handling of these American rivals could not match the Mercedes-Benz trailblazers. For those considering venturing into the four-wheel-drive vehicle market, overlooking the Mercedes-Benz M-Class, particularly the 1999 ML320, would be a significant oversight. It represented a compelling entry point into the luxury SUV segment, offering a blend of on-road sophistication and all-weather capability that set a new benchmark.
