2006 Reva G.Wiz — MOT failures & pass rate
257 MOT tests on the 2006 Reva G.Wiz are in this dataset, and 78.2% of them passed. All cars of a similar age fail 27.3% of the time, so this is 5.5pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and visibility.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 14.8% of tests against 9.3% for the next-worst category.
At component level the recurring items are headlamp aim, headlamp and washers — headlamp aim alone was recorded 21 times.
Suspension is the most common advisory, noted on 28.0% of tests — work that passed today but is likely due soon.

What to check before buying a 2006 G.Wiz
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.8% of tests. Start there.
- Lighting & signalling (14.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.3% 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.
- Visibility (8.2% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
