Should you buy a used Tvr S1?

The Tvr S1 has an overall MOT pass rate of 77.3% across 1,615 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 Tvr S1 are exhaust emissions carbon monoxide content excessive (42 recorded failures), windscreen washer provides insufficient washer liquid (34), and headlamp not working on dipped beam (32). 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 Tvr S1 owner drives around 538 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 Tvr S1 models stay on UK roads for around 39 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.
