The 2011 BMW 1 Series represents BMW's entry into the subcompact luxury segment. Available as a coupe or convertible, it offered a sporty driving experience in a smaller package. Model years for the first generation 1 Series in the US were 2008-2013. Key trims include the 128i and the more powerful 135i. New, the 2011 1 Series ranged from approximately $30,000 to $40,000 depending on the trim and options. Its rear-wheel drive setup and nimble handling made it popular among driving enthusiasts.
The Good
The 2011 BMW 1 Series offered a compelling blend of performance and practicality. Its responsive handling and powerful engines appealed to driving enthusiasts (emotional). The relatively compact size made it easy to park and maneuver in urban environments (practical). Good fuel economy for its class, especially in the 128i, added to its appeal. The classic BMW design also held its own.
The Bad
Potential weaknesses of the 2011 BMW 1 Series include relatively cramped rear seats, especially in the coupe. Reliability can be a concern with higher mileage examples, particularly with the 135i's N54 engine and its high-pressure fuel pump. Repair costs can be higher than average due to the car's European origins and complexity. The run-flat tires can provide a harsh ride and are expensive to replace.

What Problems Does the 2011 BMW 1 Series Have?
Frequently reported problems for the 2011 BMW 1 Series, particularly the 135i model equipped with the N54 engine, include issues with the high-pressure fuel pump (HPFP). This can lead to stalling or reduced engine performance. The N54 engine is also known for wastegate rattle, which is a noisy but generally harmless issue. Oil leaks from the valve cover gasket and oil filter housing gasket are also fairly common as the car ages. Some owners have reported issues with the electric water pump, leading to overheating. The 128i, with its naturally aspirated engine, generally experiences fewer major mechanical issues compared to the 135i. Recalls for the 2011 1 Series have included issues related to the fuel pump and battery cable connections. Long-term reliability can be affected by the use of run-flat tires, which are prone to damage and wear out quickly. Regular maintenance, including oil changes and fluid checks, is crucial to minimize potential problems. Carbon buildup on the intake valves is a common concern with direct-injection engines like the N54, potentially requiring cleaning or walnut blasting to restore performance.
How long will the 2011 BMW 1 Series last?
With proper maintenance, a 2011 BMW 1 Series can reasonably achieve 150,000 to 200,000 miles or more. Many owners report reaching these mileages with diligent upkeep. However, neglected maintenance can significantly shorten its lifespan. Key to long-term durability is regular oil changes, fluid checks, and addressing any emerging issues promptly. The cooling system, particularly the water pump and thermostat, can be a weak point over time. Suspension components, like bushings and shocks, may also require replacement after several years of service. Rust is generally not a major concern, but checking for corrosion, especially in areas prone to salt exposure, is always advisable.
What Technology & Safety Features are Included?
The 2011 BMW 1 Series came standard with features like a 10-speaker sound system, automatic climate control, and power windows and locks. The iDrive system, BMW's infotainment interface, was available as an option, providing access to navigation, audio controls, and vehicle settings. However, the iDrive system in this generation was less intuitive than later versions. Optional entertainment features included a premium sound system, satellite radio, and an iPod adapter. Driver-assistance features were limited compared to modern vehicles, but included dynamic stability control (DSC) and anti-lock brakes (ABS). Safety features included front and side airbags, as well as side curtain airbags for both coupe and convertible models. The NHTSA (National Highway Traffic Safety Administration) gave the 2011 BMW 1 Series a 4-star overall safety rating. The IIHS (Insurance Institute for Highway Safety) provided good ratings in most crash tests. Available options also included rear parking sensors. Remember that many features that are standard on today's cars, like a backup camera, blind spot monitoring, and adaptive cruise control, were not available on the 2011 1 Series.

Today, used market prices for a 2011 1 Series typically range from $8,000 to $15,000, depending on condition, mileage, and trim. The 135i models tend to command a higher price than the 128i, especially if they are well-maintained and have desirable options. Depreciation has been significant, as is typical for luxury vehicles.

2011 BMW 1 Series Cost of Ownership
The 2011 BMW 1 Series is generally considered moderately costly to own. Insurance rates are typically higher than average due to its sporty nature and BMW's brand reputation. Fuel costs depend on driving habits and the specific model (128i vs. 135i), but expect premium fuel requirements. Maintenance and repair costs can be significant, particularly for the 135i, due to the complexity of the engine and potential for component failures. Long-term ownership costs are heavily influenced by the owner's ability to perform basic maintenance and the car's overall condition.

How Does the 2011 BMW 1 Series Compare to Other Convertible?
The 2011 BMW 1 Series competed with vehicles like the Audi A3, Volvo C30, and even some sporty hatchbacks like the Volkswagen GTI. In terms of performance, the 135i offered a significant advantage over most competitors with its potent turbocharged engine. The Audi A3 provided a more refined interior and available all-wheel drive, but lacked the raw driving excitement of the 1 Series. The Volvo C30 offered distinctive styling and a comfortable ride, but wasn't as engaging to drive. The VW GTI offered similar levels of fun at a lower price point, but lacked the BMW's premium badge. In terms of reliability, the 1 Series, especially the 135i, lags behind the Audi A3 and VW GTI. Repair costs are also generally higher for the BMW. As a similar alternative, the Audi A3 offers a blend of luxury and practicality. The VW GTI is a more affordable and reliable option for those prioritizing performance. If rear-wheel drive isn't a necessity, the A3 and GTI represent solid choices. For those who love the BMW driving experience and are willing to accept potentially higher maintenance costs, the 1 Series remains a unique offering.

Final Verdict: Is the 2011 BMW 1 Series a Good Convertible?
The 2011 BMW 1 Series is ideal for driving enthusiasts who appreciate a sporty, rear-wheel-drive experience in a compact package. It's worth buying used if you can find a well-maintained example with a thorough service history. The 128i is generally a more reliable choice than the 135i, but the latter offers significantly more performance. A pre-purchase inspection by a qualified mechanic is essential, especially for the 135i, to identify any potential issues. Be prepared for potentially higher maintenance and repair costs compared to non-luxury brands. If you prioritize reliability and lower running costs, alternatives like the Audi A3 or VW GTI might be better choices.
