The Morris Unknown has an overall MOT pass rate of 82.5% across 548 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common problems on the Morris Unknown are stop lamp not working (10 recorded failures), headlamp not working on dipped beam (9), and body or chassis has excessive corrosion, seriously affecting its strength within 30cm of the body mountings (7). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
On the safety side, the most frequently flagged dangerous fault is parking brake efficiency less than 50% of the required value. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Morris Unknown with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.
A typical Morris Unknown owner drives around 265 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
