Should I check the MOT history before buying a 2017 Znen Zn?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2017 Znen Zn?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2017 Znen Zn?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2017 Znen Zn reliable?

Based on MOT data from 130 vehicles, the 2017 Znen Zn has a first-time MOT pass rate of 84.5%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

What are common problems with the 2017 Znen Zn?

The most frequently recorded MOT issues on the 2017 Znen Zn are: Steering headbearing has slight free play (23.3% of vehicles), COVID-19 6 MONTH EXTENSION (21.1% of vehicles), Rear Tyre worn close to the legal limit (20.7% of vehicles). These figures are based on actual MOT test records — search a specific registration on CarHunch to see its individual history.

Do I need an HPI check when buying a 2017 Znen Zn?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2017 ZNEN ZN passes its MOT first time at 84.5%, which is a solid 4.5 percentage points above the UK average of 80%, suggesting these vehicles are reasonably well-maintained overall. However, 18.5% have recorded a dangerous defect at some point, which is approaching a concern threshold and worth factoring into your purchase decision.

These machines are genuinely low-mileage for their age, averaging just 5,529 miles, which explains the relatively clean test history with fewer than one failure per vehicle on average. The high advisory count of 2.9 per car suggests minor wear items crop up regularly, so budget for small consumables—but if you're buying one, a pre-purchase inspection by a qualified mechanic will quickly reveal whether you're getting a looked-after example or one that's been neglected despite low mileage.

We have limited data for the 2017 Znen Zn — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

What tends to go wrong

Across 130 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Suspension & steering 23.3%

Steering headbearing has slight free play · Nearside Front Shock absorber has a light misting of oil · Steering headbearing has excessive wear or free play · …

Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.

Other issues 21.1%

COVID-19 6 MONTH EXTENSION

Tyre wear 20.7%

Rear Tyre worn close to the legal limit · Front Tyre worn close to the legal limit

Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.

Lighting 19%

Headlamp not working on dipped beam · Headlamp not working on main beam · Headlamp aim too low

Usually cheap to fix. Worth confirming all lights work before collecting.

Brake wear 7.9%

Rear Brake indicates slight fluctuation of brake effort · Front Brake lever is short but brake can still be readily applied · Roller brake test The less effective brake control does not achieve an efficiency of 25%

Ask the seller when brakes were last serviced. If they don't know, factor in the cost.

Exhaust & emissions 5.6%

Exhaust has a minor leak of exhaust gases
