2009 BMW Z4 3.0L Petrol · YB09 XCT

The 2009 BMW Z4 presents a current roadworthy status following a pass at 85,958 miles on 6 December 2025 with no defects recorded. The maintenance trend appears stable on paper, though the record shows two earlier failures with no listed defects, which points to administrative or unrecorded presentation issues rather than a clear mechanical decline. The most recent clean test suggests the car left the workshop in sound condition seven months before today's review date. Mileage data reveals an irregular usage pattern for a 17-year-old vehicle. The car ran 78,663 miles at the April 2023 pass, then 82,324 miles by the April 2024 pass, a modest 3,661 miles in twelve months. A sharp anomaly appears in the 15 October 2025 failure showing 138,293 miles, only to drop to 85,958 miles at the December 2025 pass. That 52,335-mile reversal is not credible as real wear and implies a clerical error or incorrect entry at the October test. Average yearly use sits near 5,056 miles, confirming light running overall. The sparse history flags no advisories on suspension bushes, brake discs, coil springs, or structural corrosion across any test. A buyer should still inspect the underside for rust given the car's age and low annual mileage, which often masks prolonged damp standing. Verify the brake calipers move freely and check exhaust emissions during a cold start. Given the two failure entries with no defects recorded, confirm with the seller what caused the 27 March 2024 and 15 October 2025 rejections. The clean December 2025 pass supports a sound purchase if those gaps are explained and a physical inspection finds no hidden wear.
