The BMW F21 M135i is a high-performance compact sedan produced by BMW from 2014 to 2019. It is powered by the N55 3.0-liter turbocharged inline-six engine and comes with an eight-speed automatic transmission. Here are some pros and cons of buying a used BMW F21 M135i with the specific engine code 643 (N55):

1. Powerful and efficient engine: The N55 engine delivers impressive power and torque, making the M135i a quick and responsive vehicle. It also offers good fuel efficiency for a high-performance car.

2. Smooth and refined transmission: The eight-speed automatic transmission is smooth and refined, providing quick and seamless gear changes.

3. Balanced handling: The M135i offers a well-balanced handling characteristic, making it fun to drive both on the track and on the road.

4. Premium interior: The interior of the M135i is luxurious and premium, with high-quality materials and advanced features.

5. Relatively low mileage cars available: Since the M135i was only produced for a few years, there are still many cars available with relatively low mileage, which can be a good option for those looking for a used performance car.

1. Maintenance costs: BMWs are known for their high maintenance costs, and the M135i is no exception. The N55 engine, in particular, can be prone to issues such as oil consumption and cooling problems.

2. Repair costs: In case of a major repair, the cost of fixing a BMW can be quite high. This is something to consider before buying a used M135i.

3. Depreciation: Like many luxury vehicles, the BMW M135i suffers from significant depreciation. This means that you may not get back the full value of your investment when you sell the car.

4. Fuel economy: While the M135i offers good fuel efficiency for a high-performance car, it still doesn't match the fuel economy of many similarly-sized sedans with less powerful engines.

The BMW F21 M135i with the N55 engine is a high-performance compact sedan that offers impressive power, refined transmission, and balanced handling. However, it also comes with some drawbacks, such as high maintenance and repair costs, significant depreciation, and relatively poor fuel economy. Ultimately, whether or not the BMW M135i is a good investment depends on your personal preferences, budget, and driving habits.

If you are in the market for a used high-performance compact sedan and have a significant budget for maintenance and repair costs, the BMW F21 M135i with the N55 engine could be a good option for you. However, if you are looking for a more affordable alternative with lower maintenance and repair costs, you may want to consider other options, such as the Volkswagen GTI or the Subaru WRX STI.
