Should you buy a used Alfa Romeo 33?

The Alfa Romeo 33 has an overall MOT pass rate of 65.1% across 3,351 real MOT tests — roughly in line with the UK average.

The most common problems on the Alfa Romeo 33 are suspension component mounting prescribed area is excessively corroded (412 recorded failures), seat belt anchorage prescribed area is excessively corroded (212), and brake pipe excessively corroded (156). 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 Alfa Romeo 33 owner drives around 1,194 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 Alfa Romeo 33 models stay on UK roads for around 40 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.
