Detailed Explanations
E21 (1975-1983): The E21 marked the beginning of the 3 Series lineage. The 320/6, equipped with a 2.0L Inline-6 engine, offered a smooth and engaging driving experience. These early models are now considered classics, prized for their simplicity and direct connection to the road. However, potential buyers should be prepared for rust issues and the challenges of maintaining an older vehicle with carburetor-based fuel delivery systems.
E30 (1982-1994): The E30 is arguably the most iconic 3 Series generation. The 320i, although not available in North America, was a popular choice in other markets, offering a balanced combination of performance and fuel economy. The E30's lightweight construction and well-tuned suspension made it a joy to drive. While rust remains a concern, the E30's relative simplicity makes it easier to maintain than later models. Its classic styling and driving dynamics have made it a highly sought-after collector's item.
E36 (1990-2000): The E36 brought a more modern aesthetic and improved handling to the 3 Series lineup. The 320i offered a decent performance upgrade over the 318i, making it a desirable option. However, the E36 is known for cooling system issues, particularly with the plastic components like the radiator and expansion tank. VANOS problems, affecting variable valve timing, are also a common concern. Careful inspection and preventative maintenance are crucial for E36 ownership.
E46 (1998-2006): The E46 is often considered the pinnacle of the 3 Series, blending a refined driving experience with improved interior quality. The 320i/320Ci, powered by a 2.2L Inline-6, provided a smooth and responsive driving experience. However, like the E36, the E46 suffers from cooling system issues, particularly the expansion tank. Subframe cracking, especially in early models, is another major concern. Oil leaks and VANOS issues are also prevalent. Addressing these potential problems proactively is essential for long-term reliability.
E90/E91/E92/E93 (2005-2013): The E90 generation introduced a wider range of body styles and engine options, including diesel variants. While the 320i models continued to offer a good balance of performance and economy, the E90 generation is known for its potential reliability issues, particularly with the N54 engine (found in the 335i, not the 320i). However, even the non-turbocharged engines are prone to oil leaks, water pump failure, and potential electrical gremlins. Thorough pre-purchase inspections and diligent maintenance are crucial for E90 ownership.
F30/F31/F34 (2012-2019): The F30 generation marked a shift towards more efficient turbocharged engines. The 320i models offered improved fuel economy and performance compared to their predecessors. However, the N20/N26 engines used in these models are known for timing chain issues and oil consumption. Charge pipe failure is another common problem. While the F30 offers a more modern driving experience and improved technology, potential buyers should be aware of these potential reliability concerns.
G20 (2019-Present): The G20 represents the latest evolution of the 3 Series, offering advanced technology and a refined driving experience. The 320i models are powered by a 2.0L Turbocharged Inline-4, providing a good balance of performance and efficiency. As a relatively new model, long-term reliability is still being assessed. However, potential buyers should be aware of the potential for software glitches and the increased complexity of modern electronics.
