Our Verdict
A solid low-mileage choice that offers good practical value, but the recent dangerous MOT failure suggests a lapse in basic maintenance. Proceed only if the recent faults have been professionally addressed before purchase.
The primary draw of this vehicle is its low mileage, which suggests less mechanical wear on the engine and gearbox. However, the May 2026 failure—specifically a 'DANGEROUS' advisory for thin brake pads and a worn disc—indicates that the previous owner neglected critical safety items. You must verify that the rear brake discs and pads have been replaced and that the damaged nearside rear tyre is a brand-new unit, not just a repair.
Check the service history meticulously for oil changes; diesel engines of this era are sensitive to Diesel Particulate Filter (DPF) issues if driven only on short trips. Given the low mileage, ensure the car has been serviced on an annual basis rather than just based on mileage, as oil degrades over time regardless of how many miles are driven.
The 1.6-litre diesel engine is relatively efficient for long-distance cruising, likely achieving 50-55 mpg depending on driving. Tax bands are mid-range for this era, and insurance groups for the ASX are typically moderate compared to more premium SUVs.
Annual running costs are estimated between £900-£1,200, accounting for fuel, tax, insurance, and routine servicing. Maintenance costs are generally predictable for Mitsubishi models, though you should budget for brake replacements as evidenced by the recent MOT history.
Pay close attention to the rear braking system. The MOT history shows a pattern of neglect, starting with advisories in 2025 leading to a major failure in 2026 for thin pads and worn discs. Test the brakes for squealing or vibration, which could indicate the recent repairs were not done properly.
Inspect the tyres thoroughly. The 2026 failure noted a cut reaching the ply cords, so ensure no other sidewall damage is present on the remaining three tyres. Additionally, check the front fog lamps, which were a point of failure in the latest test, to ensure the wiring or housing has been properly rectified rather than just having a bulb replaced.
This 2018 Mitsubishi ASX features exceptionally low mileage at 39,173 miles, well below the average for an eight-year-old diesel. While it has a long history of clean passes, the most recent MOT in May 2026 revealed significant safety issues regarding rear brakes and tyres. The 1.6L diesel engine is generally robust, but the vehicle's history indicates inconsistent preventative maintenance.
The Mitsubishi ASX is known for its mechanical simplicity and longevity, though the 1.6 DDI engine requires regular motorway driving.
