The 2005 Buick Park Avenue is a full-size luxury sedan, representing the final year of its second generation (1997-2005). It was offered in base and Ultra trims. Known for its comfortable ride, spacious interior, and traditional Buick styling, it appealed to buyers seeking a smooth, quiet, and reliable cruiser. When new, it ranged from approximately $30,000 to $35,000. Its plush ride and ample features made it a popular choice for mature drivers and those prioritizing comfort over sporty handling.
The Good
The 2005 Buick Park Avenue excels in comfort, offering a smooth ride and spacious interior. It also boasts a reputation for reliability, appealing to practical buyers. The classic, elegant design provides a sense of luxury. Its supercharged V6 offered decent performance, contributing to a feeling of effortless cruising. It represents strong value on the used market.
The Bad
The 2005 Buick Park Avenue's weaknesses include its somewhat dated styling and less-than-stellar fuel economy compared to newer vehicles. Watch out for potential issues with the air suspension (if equipped), particularly on the Ultra trim. The plastic intake manifold on the 3800 V6 can crack over time, leading to coolant leaks. Also, inspect for rust, especially in areas with road salt.

What Problems Does the 2005 Buick Park Avenue Have?
Frequently reported problems for the 2005 Buick Park Avenue often revolve around age-related wear and tear. Common issues include leaks from the intake manifold gasket, particularly on the 3800 V6 engine. This can lead to coolant loss and overheating. The air suspension, standard on the Ultra trim, is another potential trouble spot, prone to leaks and compressor failure. Repairing or replacing the air suspension can be costly; some owners opt to convert to a traditional coil spring suspension. Other concerns include issues with the power windows and door locks, which can malfunction over time. Rust can be a problem, especially in regions with harsh winters and salted roads; inspect the undercarriage, rocker panels, and wheel wells. Several recalls affected earlier model years of the Park Avenue, primarily related to electrical and fuel system components. While the 2005 model had fewer recalls than earlier years, it's still prudent to check the vehicle's VIN against the NHTSA database to ensure all applicable recalls have been addressed. Long-term reliability hinges on proper maintenance; neglected vehicles are more likely to exhibit problems.
How long will the 2005 Buick Park Avenue last?
With proper maintenance, a 2005 Buick Park Avenue can easily reach 200,000 miles or more. Many owners report exceeding this milestone with regular servicing. However, long-term durability is heavily influenced by maintenance habits. Neglecting oil changes, coolant flushes, and other essential services will significantly shorten its lifespan. The 3800 V6 engine is generally considered robust, but the plastic intake manifold can become brittle and crack with age. The air suspension (Ultra trim) is a known weak point, often requiring expensive repairs or replacement after 10-15 years. Rust is another potential issue that can affect long-term structural integrity.
What Technology & Safety Features are Included?
The 2005 Buick Park Avenue featured technology that was common for its time. Its entertainment system included a standard AM/FM radio with a cassette player and CD player. Higher trims offered an upgraded premium sound system. Tech was pretty basic, no navigation or advanced infotainment systems. Driver-assistance features were limited, including standard cruise control, anti-lock brakes (ABS), and traction control. Safety features included dual front airbags and side airbags.
Optional features included a sunroof, heated seats, and a power passenger seat. The Ultra trim had additional upgrades like massaging seats.
Crash test ratings from the NHTSA (National Highway Traffic Safety Administration) were generally positive for frontal and side impact protection. However, it's important to note that safety standards have evolved significantly since 2005. Modern vehicles typically offer a more comprehensive suite of safety technologies.
The IIHS (Insurance Institute for Highway Safety) ratings should be consulted for further assessment of safety performance, though data for this specific year might be limited.
Overall, while the Park Avenue had decent safety for its time, it lacks the advanced driver-assistance systems and modern infotainment features found in newer cars.

How Does the 2005 Buick Park Avenue Compare to Other Sedan?
The 2005 Buick Park Avenue competed with other full-size sedans like the Mercury Grand Marquis, Ford Crown Victoria, and Chrysler 300. In terms of performance, the Park Avenue offered a smooth ride, but the Grand Marquis and Crown Victoria provided a more traditional rear-wheel-drive feel. The Chrysler 300 offered more modern styling and, in some trims, more powerful engine options.
In terms of features, the Park Avenue offered a comfortable interior and decent amenities for its time, but it lacked the advanced technology of some competitors, especially in later model years.
Reliability is a strong point for the Park Avenue, with the 3800 V6 engine known for its longevity, though the air suspension on the Ultra trim can be a liability. The Grand Marquis and Crown Victoria are also considered reliable.
In terms of price, the Park Avenue is generally affordable on the used market.
Alternatives to consider include a well-maintained Mercury Grand Marquis or Ford Crown Victoria for similar reliability and traditional full-size sedan characteristics. If more modern styling and features are desired, a newer Chrysler 300 might be a better option, though it may come at a higher price point. A Lexus ES330 offers similar comfort and enhanced reliability but in a smaller package.

Final Verdict: Is the 2005 Buick Park Avenue a Good Sedan?
The 2005 Buick Park Avenue is ideal for buyers seeking a comfortable, spacious, and reliable full-size sedan at an affordable price. It's especially well-suited for those who prioritize a smooth ride and traditional styling over sporty handling or advanced technology. It's only worth buying used, as new models are obviously unavailable. A well-maintained base trim is preferable to a poorly maintained Ultra trim, as the air suspension can be a significant expense. Thorough inspection for rust and maintenance records are crucial. If you need a dependable, comfortable cruiser and are willing to address potential age-related repairs, the 2005 Buick Park Avenue can be a good value.
