The 1985 Buick Century, part of a model lineage spanning from 1973 to 1996, was a popular mid-size car known for its comfortable ride and upscale, yet accessible, styling. Available primarily as a sedan, coupe, and station wagon, it competed in a crowded segment. Key trims often included the base, the more appointed Special, and the luxurious Electra (though Electra was often a separate model name). The 1985 model year represented a refinement of its third generation. It stood out for offering a blend of American comfort and a touch of luxury without a prohibitive price tag, appealing to a broad demographic.
The Good
The 1985 Buick Century offered a smooth, comfortable ride and a quiet interior, appealing to those seeking relaxation. Its durable V6 engines provided adequate power for daily driving, and its value proposition was strong, offering a comfortable and well-equipped package for the price, making it a practical choice.

What Problems Does the 1985 Buick Century Have?
The 1985 Buick Century, like many vehicles of its era, has a number of commonly reported issues that owners should be aware of. One of the most prevalent concerns is rust, which can manifest significantly in the rocker panels, lower door skins, rear quarter panels, and around the wheel wells. This is especially true for vehicles that have lived in areas with harsh winters or significant exposure to salt.
Electrically, the Century can be prone to issues with its power accessories. Power windows, door locks, and the automatic antenna can fail. The HVAC system, including the blower motor and climate control modules, is another area where problems can arise. Dashboard warning lights may illuminate intermittently due to sensor or wiring issues. The transmission, particularly the automatic overdrive (440-T4), can be a source of concern. Failures can occur, often related to solenoid issues, clutch pack wear, or hydraulic leaks. Regular fluid changes are crucial but may not prevent all issues.
Engine-wise, the 3.3L and 3.8L V6 engines are generally considered robust, but issues like intake manifold gasket leaks (especially on the 3.8L), valve cover gasket leaks, and occasional coolant leaks can occur. The 2.5L 'Iron Duke' four-cylinder, while durable, is often criticized for its lack of power and can suffer from oil leaks.
While specific recalls for the 1985 model year that significantly impact long-term reliability are not widely highlighted as major widespread issues, it's always prudent to check the NHTSA database for any applicable recalls for a particular VIN. Generally, the long-term reliability hinges heavily on consistent maintenance and the extent of past rust damage. Many of these issues were common across GM's front-wheel-drive G-body cars of the period.

How long will the 1985 Buick Century last?
Based on owner data and anecdotal evidence, a well-maintained 1985 Buick Century can realistically see service life extending to 200,000 miles or even beyond. However, achieving this mileage is highly dependent on the owner's commitment to preventative maintenance, including regular oil changes, transmission fluid flushes, and addressing minor issues promptly. The long-term durability is significantly challenged by its susceptibility to rust, which can compromise structural integrity over time. The powertrain, particularly the V6 engines and their transmissions, can be quite durable if cared for. Weaknesses emerge primarily from environmental factors (rust) and the age-related degradation of rubber components and electrical systems, rather than inherent design flaws that would cause catastrophic failure if maintained.
What Technology & Safety Features are Included?
The 1985 Buick Century reflected the technological landscape of its era, offering a blend of standard and optional features focused on comfort and convenience. Built-in technology was relatively basic by today's standards.
Entertainment: Standard equipment typically included an AM/FM radio. Higher trims or optional packages could upgrade this to an AM/FM stereo with a cassette player. Some premium systems even offered graphic equalizers. Power antennas were often an optional upgrade for a cleaner look when retracted.
Driver-Assistance Features: Cruise control was a common and desirable optional feature, enhancing highway driving comfort. Tilt steering wheels were also often available to help drivers find a comfortable position. Power steering and power brakes were standard on most models, contributing to ease of operation.
Safety Features: Standard safety equipment included seat belts (though often lap belts in the rear for the middle passenger), padded dashboards, and collapsible steering columns designed to absorb impact. Anti-lock braking systems (ABS) were not widely available or standard on models like the Century in 1985; disc brakes were usually standard on the front, with drum brakes in the rear.
Optional Features: Beyond entertainment and convenience, optional features could include power windows, power door locks, power-adjustable seats, and air conditioning. Some higher trims might have offered intermittent windshield wipers. Exterior options included alloy wheels and upgraded paint finishes.
Crash-Test Ratings: Official crash-test ratings from organizations like the NHTSA for vehicles of this vintage are often less detailed and standardized than modern tests. However, the general design of American sedans of the mid-1980s focused on passive safety features like a sturdy passenger compartment and energy-absorbing materials. They were generally considered to offer decent protection for their time, but would not meet today's stringent safety standards.

How Does the 1985 Buick Century Compare to Other Coupe?
In 1985, the Buick Century competed in a fiercely contested mid-size segment. Key rivals included the Ford Granada/LTD, Chevrolet Celebrity (a sibling platform), Oldsmobile Cutlass Ciera, and the popular front-wheel-drive cars like the Ford Taurus/Mercury Sable (which debuted later but were in this consideration set) and Japanese offerings such as the Toyota Camry and Honda Accord.
Performance: The Century's V6 engines offered adequate, comfortable performance for the time, especially the 3.8L. It generally lagged behind some European rivals in handling dynamics but excelled in ride quality. The Taurus, in particular, offered more modern powertrains and improved handling.
Features: Buick positioned the Century as a more upscale offering within GM's lineup, often boasting plusher interiors and more available convenience features than its Chevrolet counterpart. It was competitive with other American offerings in terms of available luxury options, but Japanese sedans like the Camry and Accord began to offer a compelling blend of features and refined build quality.
Reliability: This is where the Century's reputation becomes mixed. While the V6 engines were generally robust, the GM 'J-car' derived platform (which the Century shared components with) could have electrical gremlins and transmission issues. The Taurus was also finding its feet in terms of early reliability, while the Japanese sedans often held a stronger reputation for long-term dependability and fewer electrical woes.
Price: The Century was priced competitively within the domestic market, offering a good value proposition for buyers seeking comfort and a touch of luxury without the premium price of European imports. It was generally more affordable than a comparable Mercedes-Benz or BMW, and often offered more standard features than entry-level Japanese models at a similar price point.

Alternatives:
- Similar: Oldsmobile Cutlass Ciera (very similar platform and market positioning), Chevrolet Celebrity (more budget-oriented).
- Consider: Ford Taurus (more modern, better handling, but could be pricier), Toyota Camry (excellent reliability, good efficiency, refined), Honda Accord (sportier driving dynamics, strong reliability). If a focus is on pure utility and comfort, a Ford Crown Victoria (RWD) or Chevrolet Caprice could also be considered, though they were larger and less fuel-efficient.
Final Verdict: Is the 1985 Buick Century a Good Coupe?
The 1985 Buick Century is ideal for the nostalgic driver or someone seeking an affordable, comfortable, and spacious classic American cruiser for leisurely drives and occasional errands. It's worth buying primarily as a used vehicle, particularly if you're looking for a project car or a budget-friendly classic that offers a smooth ride and a hint of 80s American luxury. Specific trims like the station wagon or models equipped with the 3.8L V6 engine are generally more desirable. Avoid models with significant rust or known transmission issues. It's not the best choice for performance enthusiasts or those prioritizing cutting-edge technology and absolute reliability compared to modern vehicles. Buying one requires a good inspection, especially for rust and electrical components, but a well-maintained example can provide enjoyable, economical motoring.
