What Problems Does the 1985 BMW 6-Series Have?
The 1985 BMW 6-Series, like many cars of its vintage, has several known issues and areas that require attention for long-term reliability. One of the most pervasive concerns is rust, particularly affecting the unibody structure, including areas around the wheel arches, rocker panels, and undercarriage. Early E24 models were more susceptible, but the 1985 model year still requires careful inspection. Electrical systems can also be a source of frustration; aging wiring harnesses, failing relays, and worn-out connectors can lead to a host of intermittent problems, from non-functioning gauges to issues with power accessories. The M30 engine, while generally robust, can suffer from head gasket failures if overheated, and leaks from oil pan gaskets and valve cover seals are not uncommon. Cooling system maintenance is critical, as old hoses and radiators can fail. The transmission, whether manual or automatic, can develop issues with age, requiring rebuilds. The limited-slip differential, if equipped, also needs its fluid changed regularly to prevent wear. Regarding recalls, specific recalls for the 1985 model year are less common in public databases compared to more modern vehicles, but general maintenance and addressing known weak points are crucial for reliability. For instance, wear on suspension bushings and ball joints is typical for a car of this age and mileage. The fuel system, including fuel pumps and injectors, can also require attention. While the build quality is generally high, time and mileage inevitably take their toll, making thorough pre-purchase inspection by a BMW specialist essential for any prospective owner.
How long will the 1985 BMW 6-Series last?
Estimating average mileage for a 1985 BMW 6-Series is challenging due to its nature as a discretionary purchase, often driven less than daily commuters. Well-maintained examples can still be found with mileage ranging from 100,000 to over 200,000 miles, showcasing their inherent durability. However, the longevity is highly dependent on the owner's commitment to meticulous maintenance, especially addressing rust and the electrical system. Without proper care, the structural integrity and electrical systems can become significant weaknesses, leading to costly repairs and a reduced service life. With diligent servicing, including regular fluid changes, timely replacement of wear items, and rust prevention, these cars can continue to provide enjoyment for many years and miles, often exceeding 250,000 miles.
What Technology & Safety Features are Included?
The 1985 BMW 6-Series offered a respectable suite of technology and safety features for its era, prioritizing driver comfort and convenience within its luxury grand touring persona. Standard technology included a premium AM/FM stereo with a cassette player, often with a graphic equalizer. Power windows, power mirrors, cruise control, and automatic climate control were also typically part of the package, enhancing the driving experience. An optional onboard computer provided basic trip information. Driver-assistance features were rudimentary by today's standards, with ABS (Anti-lock Braking System) being a significant safety innovation for the time, significantly improving braking control on slippery surfaces. Power steering was standard, offering a comfortable and manageable steering feel. Safety features included crumple zones designed into the body structure, a robust passenger compartment, and three-point seatbelts for front occupants. Head restraints for front seats were also standard. Optional features might have included a power sunroof. Crash-test ratings for vehicles from the mid-1980s are not directly comparable to modern standardized tests like those conducted by the NHTSA or IIHS. However, the E24 6-Series was engineered with a focus on structural integrity and occupant protection for its time, benefiting from BMW's reputation for building solid vehicles. The car's weight and solid construction would have provided a degree of inherent safety. While not laden with the electronic driver aids found in contemporary vehicles, the 1985 6-Series provided a well-equipped interior with an emphasis on luxury and a focus on essential safety systems like ABS, making it a sophisticated and relatively safe choice for its time.

1985 BMW 6-Series Prices and Market Value
When new, the 1985 BMW 6-Series was a premium luxury vehicle, with prices for the 635CSi typically starting in the $40,000-$50,000 range, making it an expensive proposition. Like most luxury cars, it experienced significant depreciation in its initial years. However, over time, the 1985 6-Series has transitioned from a depreciating asset to a collectible classic. Current used market prices vary widely based on condition, mileage, maintenance history, and originality. Well-maintained examples in excellent condition can fetch anywhere from $10,000 to $30,000 or even more for exceptionally rare or pristine examples. Factors affecting resale value include the presence of rust, the condition of the interior and exterior paint, mechanical soundness, and documented service history. Limited editions or desirable color combinations can also command a premium.
1985 BMW 6-Series Cost of Ownership
Owning a 1985 BMW 6-Series is generally considered costly rather than economical. Insurance premiums can be higher due to its classic/collector status and performance capabilities, though enthusiast policies may offer savings. Fuel economy is modest, typically in the mid-teens MPG, contributing to higher fuel expenses. Maintenance requires specialized knowledge, and parts can be expensive, especially for unique E24 components. Repairs, particularly for electrical issues or driveline problems, can quickly escalate costs. While the initial purchase price may be lower for a used example, ongoing maintenance, potential for unexpected repairs, and parts availability make it a financially demanding vehicle to own long-term compared to a modern, mass-produced car.

How Does the 1985 BMW 6-Series Compare to Other Vehicle?
The 1985 BMW 6-Series competed in the luxury grand tourer segment against vehicles like the Mercedes-Benz SLC/SL (R107 chassis at the time) and the Porsche 944. In terms of performance, the 635CSi offered a potent inline-six with a focus on smooth power delivery and excellent highway cruising ability, often rivaling the performance of its contemporaries. The Mercedes-Benz offered a more plush and comfort-oriented experience, while the Porsche 944 provided sharper handling and a sportier, more driver-focused feel, often at a slightly lower price point. Features-wise, the BMW was well-equipped with luxury amenities like leather interiors and automatic climate control, comparable to the Mercedes but perhaps slightly more advanced in certain electronic features than the 944 of that era. Reliability is a mixed bag for all these cars. BMWs of this vintage are known for robust engines but can be susceptible to electrical gremlins and rust. Mercedes often held an edge in overall durability and rust resistance. Porsche 944s are generally reliable but can have specific maintenance needs. Price-wise, the BMW 6-Series was typically positioned at the higher end, similar to or slightly below the comparable Mercedes SL, and often more expensive than the 944. Alternatives to consider for similar driving experiences would include the Mercedes-Benz 560SL (R107), which offers more V8 power and legendary Mercedes build quality, though often at a higher price. For a sportier feel with excellent handling, the Porsche 944 is a strong contender, often more affordable to purchase and maintain. Another option could be a Jaguar XJ-S, offering a different flavor of British luxury and V12 power, though with its own set of reliability considerations. If a similar classic BMW coupe is desired but with a slightly different emphasis, an E30 M3 (if budget allows) offers unparalleled driving dynamics, or a well-preserved E28 5-Series sedan provides much of the same mechanical goodness in a more practical package.
Final Verdict: Is the 1985 BMW 6-Series a Good Vehicle?
The 1985 BMW 6-Series is ideal for the discerning automotive enthusiast who appreciates classic European styling, a powerful yet refined inline-six engine, and the experience of a true grand tourer. It's worth buying for those who value its timeless design, driving pleasure, and potential for appreciation as a collectible. However, it is crucial to buy a well-maintained example, preferably with extensive service records and minimal rust, as repair costs can be substantial. Focus on the 635CSi trim for the best balance of performance and luxury. This is not a car for the budget-conscious buyer or someone seeking trouble-free daily commuting without a significant commitment to maintenance and potential repairs. Buying a solid, well-cared-for car is paramount to a positive ownership experience.
