If you’re considering buying a 2013 BMW Z4 sDrive20i M Sport, one of the biggest questions is simple: how much does it actually cost to own per year in the UK?

Here is a real-world 2025 cost breakdown, including mandatory expenses, maintenance, fuel, and projected 2026 costs.

These are the fixed annual costs required to legally keep the car on the road in the UK.

• MOT: £50

• Insurance: £234

Total Mandatory Costs: £549

For a 2.0-litre turbocharged rear-wheel-drive roadster, these costs are relatively reasonable compared to higher-powered variants.
