2007 Reva G.Wiz — MOT failures & pass rate
Across 462 MOT tests, the 2007 Reva G.Wiz recorded an 84.6% pass rate. Against all cars of a similar age (26.9% fail rate), the 2007 G.Wiz comes out 11.5pp better. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 18.6% of all tests — 13.2 points clear of suspension, so it is the first thing to check.
At component level the recurring items are headlamp aim, headlamp and position lamp — headlamp aim alone was recorded 46 times.
Advisories point at the next bill rather than this one: suspension was flagged on 22.5% of tests without failing them.
The trend is improving — the fail rate fell from 15.6% in 2021 to 12.5% in 2025, as the worst-kept examples leave the fleet.

| 0-30k | 328 | 16.5% |
| 30-60k | 109 | 12.8% |

What to check before buying a 2007 G.Wiz
On a 2007 G.Wiz, lighting & signalling is what the MOT record says goes wrong most — it appeared in 18.6% of tests. Check these areas before you commit.
- Lighting & signalling (18.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.4% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (3.9% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
