The 1987 Mercedes Benz 420sel represents a pinnacle of automotive engineering from an era renowned for its robust construction and timeless design. For enthusiasts and those considering a classic luxury vehicle, the W126 series, and specifically the 420SEL model, continues to hold significant appeal. A common point of interest, especially when considering a vehicle of this vintage, is mileage. A well-maintained 420SEL with around 95,000 miles is indeed noteworthy, suggesting a car that has been enjoyed but not excessively worn.
Addressing Common Concerns: Sunroof and Starting Reliability
One frequently discussed feature of the W126 Mercedes is the sunroof. Concerns about expensive repairs are valid, but often, preventative maintenance can mitigate potential issues. In many cases, a sticky sunroof is not indicative of major mechanical failure. Instead, the tracks may simply require thorough cleaning and lubrication. Similarly, the sunroof cable might need adjustment after years of inactivity. Addressing these maintenance points can often resolve sunroof sluggishness without resorting to costly repairs. However, it’s worth noting that genuine mechanical problems can lead to repair bills in the $700+ range at some service centers. The silver lining is if the sunroof is not leaking, a significant hurdle is already overcome.
Starting reliability in the 1987 Mercedes Benz 420SEL is typically robust. These cars were equipped with substantial batteries, often described as feeling akin to heavy-duty truck batteries. This ample power reserve ensures confident starting, even after periods of inactivity.
Fuel Economy: Highway Efficiency Surprises
Fuel economy is naturally a consideration for any car, and particularly for a classic V8 luxury sedan. Official figures for the 5.6-liter V8 in the 560SEL were around 17 mpg city and 19 mpg highway. While the 1987 Mercedes Benz 420SEL, with its slightly smaller 4.2-liter V8, offers modestly improved figures, real-world experience often surpasses expectations, especially on long journeys. Owners frequently report exceeding 415 miles on a single tank while cruising at 70-80 mph, even with hilly terrain. This highway efficiency can be surprising for a vehicle of this size and age. The perception of fuel consumption in older cars might also be influenced by potentially more honest reporting standards of the time. Modern fuel economy figures can sometimes be less representative of real-world driving, particularly when exceeding optimal speeds or encountering inclines.
In direct comparisons, the 1987 Mercedes Benz 420SEL can hold its own, even against more contemporary, supposedly fuel-efficient cars on the open road. Anecdotal accounts describe scenarios where a W126 Mercedes outperforming a modern Honda Accord in cross-country trips in terms of fuel stops, hill climbing ability, and overall driver fatigue, despite the Accord theoretically being more economical. However, it’s acknowledged that in city driving, the V8 engine of the 420SEL will consume more fuel compared to smaller, modern engines. This trade-off is often accepted as part of the experience of owning a classic luxury car.
For those prioritizing fuel frugality without sacrificing the comfort and prestige of the W126, the 300SDL, with its diesel engine, presents a compelling alternative. While offering reduced power and acceleration compared to the 1987 Mercedes Benz 420SEL, the 300SDL delivers significantly improved fuel economy while retaining the luxurious appointments and ride quality characteristic of the W126 series.
In conclusion, the 1987 Mercedes Benz 420SEL remains a desirable classic, offering a blend of robust engineering, luxurious comfort, and surprisingly capable performance. While factors like sunroof maintenance and city fuel economy should be considered, the overall ownership experience, particularly for highway driving and classic car enthusiasts, continues to be rewarding.
