The MG Zr 105 has an overall MOT pass rate of 74.2% across 267 real MOT tests — roughly in line with the UK average.
The most common problems on the MG Zr 105 are tyre tread depth below requirements of 1.6mm (18 recorded failures), windscreen wiper does not clear the windscreen effectively (11), and track rod end ball joint has excessive play (10). 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.
A typical MG Zr 105 owner drives around 4,872 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.
In terms of longevity, most MG Zr 105 models stay on UK roads for around 22 years — a strong showing that suggests solid build quality and readily available parts. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
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.
