Key Considerations When Buying a Used BMW M8
The M8 and M8 Competition, having been released only a few years ago, benefit from BMW's latest technology and manufacturing standards, meaning there are few widespread issues to worry about compared to older models. However, as with any used vehicle, certain factors should be considered to ensure that the car you’re buying is in good condition and well-maintained.
1. Verify Service History
The M8 is a high-performance vehicle, and as such, it requires regular servicing and maintenance to ensure it performs optimally. When purchasing a used M8, ensure that the service history is complete and up-to-date. Regular servicing is crucial for maintaining the car's mechanical integrity, especially when it comes to the engine, transmission, and suspension. A well-documented service history from a BMW-approved dealership is a good indication that the car has been properly cared for.
2. Check for Track Use
While the M8 is more focused on luxury and refinement than outright track performance, some owners may have used the car on track days. If you suspect that the car has been driven aggressively or on track, check for signs of excessive wear. Look for signs of chassis play, damage to the suspension components, or excessive tyre wear, particularly on the inner edges. These could be indicative of heavy use, which may affect long-term reliability.
3. Inspect the Bodywork and Paint Condition
The M8 features a refined and stylish design, so it’s essential to inspect the bodywork carefully for any signs of damage, scratches, or imperfections. Pay close attention to areas such as the bumpers, side skirts, and wheel arches, as these are common areas prone to cosmetic damage. A thorough inspection for any signs of paintwork repair or mismatched paint can indicate previous accidents or minor collisions.
4. Review the Condition of the Wheels and Tyres
As a performance car, the M8 is fitted with high-performance tyres, which can wear quickly if the car is driven hard or aggressively. Check the tyres for uneven wear, especially on the inner edges, which could be a sign of poor alignment or aggressive driving. Ensure that the wheels are free from damage or curbing, as these can affect the car's handling and potentially indicate a lack of attention to detail by previous owners.
5. Test the Electronics and Features
The M8 is loaded with advanced technology, including a sophisticated infotainment system, active safety features, and driver-assistance systems. It’s important to test all of these features thoroughly to ensure that everything is working as it should. Check the functionality of the navigation system, Bluetooth connectivity, adaptive cruise control, and the dynamic driving modes. If anything is malfunctioning or doesn’t work as expected, it may be costly to repair or replace.
Important Considerations for Performance and Usage
While the M8 is built to be a high-performance car, its weight and complex drivetrain mean that careful attention to maintenance is important to keep it running at its best.
1. Engine and Cooling
The M8 is powered by the 4.4-litre twin-turbo V8 engine, producing up to 617 bhp in the Competition version. This engine is capable of incredible performance but places significant stress on the cooling and engine management systems. Ensure that the vehicle has been regularly serviced, and check for any signs of overheating or coolant leaks, particularly around the radiator and turbochargers.
2. Transmission and Drivetrain
The M8 comes equipped with BMW's 8-speed dual-clutch transmission (DCT), offering fast and smooth gear changes. However, given the weight and performance of the car, the drivetrain components can wear more quickly than in standard BMW models. Pay attention to any irregularities in shifting, hesitation, or noises coming from the transmission. Additionally, check the condition of the drive shafts and differential, particularly if the car has been used aggressively.
3. Suspension and Handling
The M8 is a relatively heavy car, and the suspension is a crucial element in maintaining its performance. Look for any signs of wear in the suspension components, including the shocks, springs, and bushings. The M8 features adaptive suspension settings, which can be adjusted for different driving conditions, so be sure to test the system and make sure it is functioning correctly. If the car has been used on track or driven aggressively, it may show signs of suspension fatigue.
4. Brakes
Given the power of the M8, it is important to check the condition of the braking system. Look for any signs of worn brake pads or discs, as well as any unusual vibrations or noises when braking. The M8 uses high-performance carbon-ceramic brakes in the Competition models, which offer improved performance and longevity but are more expensive to replace. If the car you’re looking at has the carbon-ceramic brakes, be sure to inspect them carefully and ask if they’ve been replaced or serviced recently.
Maintenance and Ownership Costs
Owning an M8 comes with higher-than-average maintenance costs due to its performance-oriented design and advanced technology. Routine servicing is essential, including oil changes, brake fluid replacements, and checks on the suspension and drivetrain. If the car has been modified or tuned, expect additional maintenance requirements to keep the car running smoothly.
For cars with more aggressive driving or track use, more frequent maintenance may be necessary. This includes additional checks on the engine, transmission, suspension, and cooling systems. Keep in mind that parts such as the tyres, brakes, and clutches may need to be replaced more often in performance-oriented cars, especially if the car has been used on track.

While these vehicles are relatively new, it’s important to verify the service history, check for any signs of heavy use or track involvement, and ensure that all systems are functioning correctly before making a purchase. With proper maintenance, the M8 can provide years of driving pleasure, combining track-worthy performance with everyday usability.
