The most common problems on the Austin Allegro Hl are suspension component mounting prescribed area is excessively corroded (98 recorded failures), subframe mounting prescribed area is excessively corroded (50), and seat belt anchorage prescribed area is excessively corroded (40). 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.

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.
