Buying Tips for the 2022 BMW Z4 (G29)
- ✓Check the fabric soft-top for any wear marks or creases, and ensure it opens/closes silently in the claimed 10 seconds.
- ✓Inspect the B48/B58 engine water pump and thermostat area for slow coolant leaks, a common minor issue on modern BMWs.
- ✓Test the iDrive 7 digital instrument cluster to ensure it doesn't freeze or lag, verifying the car has the latest OTA software updates.
- ✓Verify the condition of the large alloy wheels, as the low stance makes them very susceptible to kerbing.
- ✓Ensure the active exhaust valves (if fitted) open and close correctly when switching between Comfort and Sport modes; they can seize with carbon buildup.
- ✓Check the interior trim for squeaks, particularly around the rear bulkhead where the roof mechanism meets the cabin.
