2015 Vauxhall Insignia 2.0L Diesel · DL15 TVK

The Vauxhall Insignia presents a current roadworthy status following a pass on 25 March 2026 at 306,317 miles, with the maintenance trend appearing stable across its recorded history. The most recent test shows no defects, though the prior day's failure at 306,276 miles is anomalous as the DVSA record lists no defects against that test. This suggests an administrative or procedural rejection rather than a mechanical fault, and the immediate subsequent pass confirms the vehicle cleared requirements without rectification. Mileage accumulation on this 2015 model is exceptionally high at 306,317 miles over roughly eleven years, averaging near 27,847 miles annually. The record shows 112,635 miles in May 2023, 141,688 in May 2024, and 168,353 in May 2025, a steady ~29,000 miles per year. A sharp jump to 306,317 by March 2026 indicates roughly 138,000 miles added in ten months, pointing to intensive commercial or high-mileage commuting use rather than private neglect. No MOT data exists before 2023, leaving the early-life care pattern unverified. Given the clean advisory history with no flagged suspension bushes, brake discs, coil springs, or corrosion across all five tests, the buyer should still commission an in-person inspection of structural integrity and drivetrain wear. The extreme 306k mileage demands scrutiny of the clutch, turbo, and timing chain where applicable, plus underbody rust and subframe condition not always caught in a test lane. The 2026-03-24 failure with zero listed defects warrants confirmation the V5C and DVSA entry carry no suppressed rationale. High mileage with sparse early records implies the prior owner prioritised keeping the car legally tested rather than documenting preventative care. A pre-purchase mechanical assessment by a Vauxhall specialist remains prudent before commitment.
