Is It Worth Buying an Old BMW for Reliability?
When considering the purchase of an old BMW, reliability is one of the most important factors to evaluate. Despite the commercials depicting BMW as the epitome of luxury and engineering excellence, there are certain aspects of older BMWs that make them less desirable in terms of cost and durability.
Over-Engineering and Reliability
No doubt, BMW has built excellent cars, but the tendency to over-engineer every component can lead to complex and sometimes expensive issues when something goes wrong. A notable example is the regenerative braking system used in certain older models. While this system is efficient in terms of energy recovery and 12V battery charging, it is quite complicated and expensive to repair when it malfunctions. Additionally, most BMWs use a conventional alternator, which also contributes to the overall reliability and cost.
The complexity inherent in the design of these systems means that they have more components that can fail, and the costs associated with repairs can be substantial. This design philosophy, while providing a high level of precision and efficiency under ideal conditions, does not always translate into a cost-effective or easily maintainable car in the long run.
Part Availability and Finicky Problems
Another significant challenge with older BMWs is the availability of parts. As these cars age, parts can become harder to find, which can lead to delays in repairs and potentially more costly solutions. Finicky parts that are prone to leaks or breaking can add to the frustration and financial burden of owning an older BMW.
The reliability of an older BMW can vary greatly depending on the specific model and engine. While some pre-2012 models with engines like the M50, M52, and M54 can offer the reliability of a well-maintained Honda, other models are less forgiving. The N54 turbo engine and the N63 V8 engine are particularly notorious for their issues. The N20 engines, introduced around 2007, were also plagued with problems, making them a less reliable choice for older BMWs.
Cost and Maintenance
The maintenance costs for older BMWs can be quite high. A key factor is the availability and cost of essential components such as alternators, brakes, and many other parts. Labor costs, which are often higher for luxury brands, can significantly impact the overall cost of maintaining these vehicles.
When comparing other makes, such as Toyota and Honda, it is clear that they offer more reliable and cost-effective options. While BMWs provide a driving experience that is superior in terms of performance and handling, the high maintenance and repair costs can outweigh the benefits for many drivers.
Leasing BMWs is more common than purchasing them due to the higher costs and potential for unexpected repairs. This market trend reflects the challenges faced by owners of older BMWs.
So, if you are considering buying an old BMW, it is crucial to weigh the potential reliability issues against the need for a premium driving experience. If reliability and cost-effectiveness are top priorities, sticking to more reliable makes like Toyota and Honda might be a better choice.
