BMW X3M/X4M F97/F98 Buying Guide
BMW X3M/X4M F97/F98 Buyers Guide
The BMW X3M and X4M, equipped with the potent S58 engine, offer a compelling combination of performance, luxury, and utility. As part of BMW's high-performance M range, these SUVs deliver the thrilling driving dynamics expected of an M car, while still offering the versatility of an SUV. For those looking to purchase a used X3M or X4M, this guide outlines key factors to consider, ensuring you make an informed decision when selecting your next performance SUV.
Performance and Driving Dynamics
The X3M and X4M are both equipped with the 3.0-litre, twin-turbocharged S58 engine, producing up to 510 hp in the Competition models. This engine is paired with an 8-speed automatic transmission and BMW's xDrive all-wheel-drive system, ensuring robust performance and handling, even for a vehicle of this size and weight. It’s important to remember that these are large, heavy vehicles, with the X3M and X4M weighing in at over 2,000 kg (approximately 4,400 lbs). As such, while they offer impressive performance, buyers should bear in mind that these vehicles may not offer the same agility as lighter, more compact performance cars.
What to Look for When Buying a Used BMW X3M/X4M
While the X3M and X4M are relatively new models and many will still be under warranty, there are still several important factors to consider before purchasing a used one.
1. Service History
A full service history is essential when purchasing any used vehicle, but especially when it comes to high-performance cars like the X3M and X4M. Ensure that the car has been serviced according to the manufacturer’s schedule, and preferably by an authorised BMW dealer. Service records should include details of oil changes, brake fluid replacements, and any other required maintenance. For performance vehicles like these, regular servicing is critical to maintaining optimal performance and reliability. If the vehicle has had any modifications, check whether they were carried out by reputable specialists and whether the car has been re-mapped or tuned in any way.
2. Tyre Wear and Condition
Tyres are crucial for maintaining performance, especially in high-powered M models like the X3M and X4M. Given the weight and power of these vehicles, tyre wear can be accelerated, particularly if the vehicle has been driven hard or used aggressively. Inspect the tyres for uneven wear, particularly on the inner edges, which could indicate alignment issues. It's also worth checking the age of the tyres, as rubber compounds degrade over time, regardless of how much they’ve been driven. Replacing tyres on an X3M or X4M can be expensive, so it's worth ensuring they have sufficient tread and are of the correct specification.
3. Suspension and Handling
The X3M and X4M come equipped with adaptive suspension systems designed to balance comfort and performance. Given the vehicle's size and performance potential, the suspension system is integral to the driving experience. Be sure to inspect the suspension components for any signs of wear or damage. Check for excessive noise, clunking, or any irregularities when driving, as these could point to worn shock absorbers, bushings, or other suspension components. The adaptive suspension should switch between comfort and performance modes smoothly, and any issues in this regard could indicate potential repair costs.
4. Brakes
With performance comes the need for high-performance brakes. The X3M and X4M are equipped with powerful braking systems that are essential for controlling the vehicle's speed, particularly at high velocities. Check the condition of the brake pads and discs. Uneven wear or excessive brake dust may be signs of aggressive driving. Additionally, pay attention to any vibrations or noises when braking, as this could indicate issues with the brake system, such as warped discs or worn pads.

5. Exterior and Interior Condition
Given the performance nature of the X3M and X4M, some buyers may be tempted to use these vehicles for track days or spirited driving. Be sure to carefully inspect the exterior for any signs of cosmetic damage, dents, or scratches, particularly around the bumpers and wheel arches. Also, check for signs of curbing or damage to the alloy wheels, as these may point to aggressive driving. Inside the vehicle, check for signs of wear on the seats, steering wheel, and dashboard. High-performance vehicles like the X3M and X4M can suffer from faster interior wear if driven frequently and aggressively.
6. Test Drive
Before purchasing any used vehicle, always take it for a test drive. The X3M and X4M should feel responsive and composed, both in a straight line and when cornering. Pay attention to any unusual noises, such as rattles, clunks, or vibrations, as these could indicate underlying issues. The steering should be precise, and the vehicle should feel stable at high speeds. In addition, test all of the car’s driving modes, as the adaptive suspension, throttle response, and steering feel will change depending on whether the car is set to Comfort, Sport, or Sport+ mode.
Performance Considerations
While the X3M and X4M are certainly capable of thrilling performance, it’s important to remember that these vehicles are large, heavy SUVs. As such, while their acceleration and handling are impressive, they will not behave like lighter, more agile performance vehicles such as the M3 or M4. However, their combination of power, all-wheel drive traction, and adaptive suspension make them incredibly capable machines that can excel in both everyday driving and spirited, performance-oriented use. If you plan on using the car for track days or more aggressive driving, you may want to consider the impact this will have on the suspension, tyres, and brakes, all of which will require more frequent attention.
Maintenance and Ownership Costs
Like any high-performance BMW, the X3M and X4M come with higher-than-average maintenance costs. Regular servicing, tyre replacements, and brake maintenance are all key to keeping these vehicles in peak condition. Additionally, if you’re purchasing a used model, it’s important to ensure that the vehicle is still under the BMW warranty, which typically lasts for 3 years or 60,000 miles (96,000 km), whichever comes first. If the warranty is expired, you may want to consider purchasing an extended warranty for peace of mind, as repairs on performance SUVs like the X3M and X4M can be costly.
