Should you buy a used Suzuki SP370?

The Suzuki SP370 has an overall MOT pass rate of 83.4% across 633 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 Suzuki SP370 are horn not working (9 recorded failures), stop lamp does not illuminate immediately a brake applies (8), and direction indicator not working (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.

A typical Suzuki SP370 owner drives around 139 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 Suzuki SP370 models stay on UK roads for around 48 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.
