BMW M5 F90 Buying Guide
BMW M5 F90 Buying Guide
The BMW M5 F90, introduced in 2017, is the latest iteration of BMW's iconic M5 performance sedan. Equipped with the powerful 4.4-litre twin-turbo V8 engine and boasting impressive performance figures, the M5 F90 is a true powerhouse that offers both luxury and track-ready dynamics. If you're considering purchasing a used M5 F90, there are several key factors to consider to ensure you're making an informed decision. This guide will provide you with useful tips on what to look for when buying a used M5 F90, as well as essential maintenance considerations.
Key Considerations When Purchasing a Used BMW M5 F90
1. Vehicle History and Service Records
Before committing to a used M5 F90, it’s essential to review the vehicle’s history. Make sure to check for:
- Service Records: Look for evidence of regular servicing, especially at authorised BMW dealers. A well-maintained M5 F90 should have had oil changes, fluid replacements, and inspections completed as per BMW’s recommended schedule.
- Accident History: A full history report can highlight any accidents or significant repairs, which might impact the car’s value or performance.
- Ownership History: Fewer owners generally mean less chance of inconsistent care. If the car has been in the hands of multiple owners, it’s important to ensure each has properly maintained the vehicle.
2. Mileage
Mileage plays a significant role in determining the value and longevity of a used M5 F90. While the M5 is designed to be a high-performance vehicle, it's important to consider:
- Low to Mid Mileage: Ideally, a used M5 should have mileage below 50,000 miles (80,000 km). Lower mileage cars often come with fewer signs of wear, though the condition and maintenance history are far more important.
- High Mileage: If you're considering a higher-mileage example, ensure that critical components, like the transmission, engine, suspension, and drivetrain, have been thoroughly inspected or serviced. High-mileage cars may require additional investment in maintenance.
3. Condition of the Exterior and Interior
The M5 F90 is a premium sports sedan, and its condition should reflect this. Pay close attention to both the interior and exterior:
- Exterior: Check for signs of wear or damage, such as dents, scratches, or corrosion, particularly around the front end and lower sills. Also, assess the condition of the wheels—kerbing is common, but excessive damage could indicate rough driving.
- Interior: The quality of the interior should remain high. Check for any wear on the seats, dashboard, or other high-use areas. Pay attention to any electronic issues, such as the infotainment system, as repair costs can be significant.
4. Performance and Test Drive
Given the M5 F90's performance-oriented nature, a test drive is essential to ensure everything runs smoothly. Key points to evaluate include:
- Engine Performance: The M5 F90 is equipped with a 4.4-litre twin-turbo V8 producing over 600bhp. During the test drive, check for any unusual sounds, misfires, or hesitation when accelerating. The engine should feel strong and responsive at all rev ranges.
- Transmission and Gear Changes: The M5 F90 comes with an 8-speed dual-clutch automatic transmission. The gear shifts should be smooth and quick, with no jerking or delays. If the car has the optional rear-wheel-drive configuration, ensure the car handles well during aggressive cornering.
- Braking and Suspension: The M5 F90 features adaptive suspension and a high-performance braking system. Check for any unusual vibrations, noises, or lack of responsiveness when braking. The suspension should provide a firm yet comfortable ride, and the car should stay flat during high-speed cornering.
5. Common Issues and Maintenance
The M5 F90 is generally a reliable vehicle, but like any high-performance car, it can experience specific issues. Some things to look out for include:
- Turbochargers: The 4.4-litre twin-turbo V8 engine in the M5 F90 can be susceptible to turbocharger issues if maintenance is neglected. Listen for any abnormal sounds or lack of power delivery during your test drive.
- Braking System: The M5 is equipped with high-performance brakes, which can wear quickly, especially if the car has been driven aggressively. Make sure the brake pads and discs are in good condition.
- Electronics and Infotainment: The M5 F90’s complex electronic systems can sometimes suffer from issues, especially with the infotainment or driving assistance systems. Ensure everything functions as expected, including the display, cameras, and parking sensors.
- Drivetrain and Transmission: Ensure the gearbox shifts smoothly and that there is no sign of drivetrain wear, such as knocking noises or difficulty engaging gears.
Maintenance Considerations for the BMW M5 F90
When it comes to maintaining the M5 F90, there are a few key aspects to keep in mind:
- Regular Oil Changes: As with any high-performance engine, regular oil changes are crucial for longevity. The M5 F90’s engine should have its oil changed every 10,000 miles (16,000 km) or 12 months, whichever comes first.
- Brake Fluid and Pads: The M5’s high-performance braking system should be maintained regularly. Replace brake fluid every 2 years and inspect the brake pads for wear. Track use or aggressive driving will wear pads more quickly, so be prepared for earlier replacements.
- Transmission Fluid: The dual-clutch transmission is generally low-maintenance, but it’s still essential to check the fluid level and condition periodically. BMW recommends a fluid change every 30,000 miles (48,000 km), but this may vary depending on driving style.
- Tire Care: High-performance tyres wear out more quickly, particularly if the car is used on track or driven aggressively. Regularly check the tread depth and replace tyres as necessary to maintain performance.
- Suspension and Alignment: The adaptive suspension should be checked regularly, particularly if the car has been driven aggressively or used for track days. The alignment should also be checked if the car pulls to one side or if steering feels off.
Final Thoughts
The BMW M5 F90 is a high-performance sports sedan that offers an exceptional driving experience. When purchasing a used M5 F90, ensure you review the vehicle’s service history, perform a thorough inspection, and take the car for a test drive to evaluate its performance. Look out for common issues, such as turbocharger and brake wear, and ensure that any potential maintenance or repairs are taken into consideration when negotiating the price. With proper care, the M5 F90 will continue to provide thrilling performance and luxury for many years to come.
