The 2004 MINI One passes its MOT first time in only 71.6% of cases, well below the UK average of 80%, and nearly half of these cars (48.3%) have recorded a dangerous defect at some point—a significant reliability red flag for a buyer. With an average of 5.91 failures per vehicle and 41 advisories, these Minis are prone to multiple issues rather than isolated problems.
At 76,000 miles average, these are reasonably well-used examples for their age, yet the high failure count suggests age and wear take a real toll. Before buying, get a pre-purchase inspection to check the brakes, suspension, and electrical systems, as the advisory data points to recurring issues in these areas typical of ageing Minis.

Brake pipes, sills and subframes are the key areas on a vehicle this age — structural rust is hard to spot without getting underneath. A mechanic will check all of this before you commit, and give you a concrete basis to negotiate on price.
