Why the BMW Z4 is so cheap: 5 key reasons
1. The limited uses inherent to open-top cars
The BMW Z4 is a two-seater convertible , which means it has the following limitations:
- No rear seats, so not suitable for families
- Limited luggage space makes it inconvenient for travel and shopping
- It is easily affected by weather and cannot be used comfortably all year round.
- There are times when it is difficult to maneuver in Japan’s narrow road environment.
In the Japanese market, demand for convertibles is limited compared to Europe and the United States. , which is a major factor in the price decline.
2. Concerns about high maintenance and repair costs
Maintaining a BMW Z4 is more expensive than maintaining a domestically produced car:
Estimated annual maintenance costs
- Automobile tax : 39,500 yen to 51,000 yen
- Optional insurance : 100,000 to 150,000 yen
- Vehicle inspection and maintenance fee : 100,000 to 200,000 yen
- Fuel costs (10,000km per year): 120,000 to 150,000 yen
- Consumables and repair costs : 80,000 to 150,000 yen
Total: Approximately 350,000 to 700,000 yen per year
The following parts are particularly at risk of failure and are known to be expensive to repair:
- Electric soft top mechanism : 100,000 to 200,000 yen
- DSC unit : Parts alone cost over 300,000 yen
- Ignition coil : 10,000 to 20,000 yen per coil
3. The complexity of parts procurement and maintenance unique to imported cars
Maintaining a BMW Z4 presents the following challenges:
- Genuine parts are expensive : 2 to 3 times the price of domestically produced cars
- The need for mechanics with specialized knowledge
- Difficulty in repairing outside of the dealership
- Expertise in fault diagnosis equipment
These factors have led to the impression that they are difficult to maintain, reducing their popularity as used cars.
4. The value of existing models falls as new models are introduced
The BMW Z4 is updated on a roughly 10-year model cycle, and when a new model is released, the value of the old model tends to plummet:
- When the G29 model was released in 2019, the used car price of the E89 model dropped significantly.
- A relative decline in the appeal of the latest safety features and performance
- Reduced trade-in value at BMW dealerships
5. Its “controversial” position as a sports car
The market is polarized when it comes to the BMW Z4:
Positive evaluation
- Excellent handling performance
- A beautiful open-air driving experience
- High-quality driving experience typical of BMW
Negative evaluation
- Some people say it has “half-baked sports performance”
- Low practicality for everyday use
