Road tax is cheap thanks to the Euro 6 DG classification, sitting in a low VED band of around £20-£30 per year after the first-year rate has expired. Insurance for a 2020 Focus diesel in the UK typically falls into groups 12-15, placing it in the £450-£650 annual bracket for most drivers. Routine maintenance is relatively affordable, with a major service including oil, filter and Diesel Particulate Filter additives typically costing £200-£300 at an independent garage.

Start with a close look at the rear brakes, since the 2024 MOT flagged worn offside rear discs and pads - inspect both sides for lipping, scoring and remaining pad thickness. The 1.5 TDCi engine is known for potential EGR cooler and inlet manifold carbon build-up, particularly on high-mileage or short-journey examples, so check for black soot deposits around the EGR area and any hesitation under load. The Dual-clutch automatic (PowerShift) versions of this Focus have a known reliability concern, but this 1.5 diesel is more commonly paired with a manual or conventional torque converter automatic, so confirm the gearbox type and check for smooth shifts. Examine the underbody and wheel arches for corrosion, as Ford Focus models of this era can show early rust on rear suspension components and the boot floor. Finally, verify the DPF condition by checking for warning messages and ensuring the vehicle completes regular motorway runs, as diesel DPFs clogged from urban use can lead to expensive replacement.
