2020 BMW Z4 2.0L Petrol · CAZ 4

The 2.0-litre petrol Z4 typically returns around 40-45 mpg on a mix of journeys, depending on driving style, though enthusiastic use will push this considerably lower. As a Euro 6 DG compliant petrol registered after April 2017, road tax sits in the standard £190 to £195 annual band for this emissions class. Insurance for the Z4 generally falls into groups 30-35 depending on the exact variant, so premiums will be higher than a family hatchback but manageable for an experienced driver. Routine servicing costs are typical of premium German marques, with brake fluid, oil, and filter changes broadly in line with BMW 3 Series equivalents, though tyres on a sports car tend to wear faster. Estimated annual running costs land in the £1,400-£1,800 range, covering fuel, tax, insurance, and routine maintenance.

The front tyre advisory from December 2025 should be the starting point for any inspection. Uneven edge wear on both front tyres simultaneously often points to misalignment, worn suspension bushes, or damaged coil springs, and coil springs are flagged as a top MOT failure reason for the Z4 model overall. Check the front tyres directly and inspect the springs, top mounts, and anti-roll bar linkages, the latter also appearing in the model's top failure reasons. The 2.0-litre engine should be started from cold if the seller allows, and listen for any timing chain rattle or auxiliary belt noise. On the bodywork, inspect the fabric or hardtop roof (depending on specification) for correct operation, and examine the rear arches and sill edges for any signs of kerbing damage, which is common on a low-slung sports car. Finally, verify that all warning lights extinguish promptly on ignition and that the iDrive system functions correctly, including sat-nav and climate control.
