Should I check the MOT history before buying a 2003 Sym Jet?

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 2003 Sym Jet?

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 2003 Sym Jet?

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 2003 Sym Jet reliable?

Based on MOT data from 428 vehicles, the 2003 Sym Jet has a first-time MOT pass rate of 82.2%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

What are common problems with the 2003 Sym Jet?

The most frequently recorded MOT issues on the 2003 Sym Jet are: Rear Tyre worn close to the legal limit (24.4% of vehicles), Headlamp at least one does not illuminate on dipped beam (14.7% of vehicles), Exhaust slightly deteriorated (13.5% 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 2003 Sym Jet?

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.

Moderate sample. 428 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2003 SYM JET passes its MOT first time in just 66% of cases, well below the UK average of 80%, which signals reliability concerns for this ageing scooter. The dangerous defect rate of 8.9% is modest enough not to be a major red flag, but nearly one in three will need work to pass inspection.

These machines are running with relatively low mileage for their age—averaging 14,100 miles—yet still failing at a high rate, suggesting age and wear rather than abuse is the culprit. Expect an average of 0.87 failures and 1.9 advisories per test, meaning routine maintenance and minor fixes should be budgeted in; before buying, have any candidate inspected by a scooter specialist, as a 21-year-old SYM needs thorough vetting beyond the MOT itself.

The 2003 Sym Jet passes its MOT first time at roughly the UK average rate (82.2%) — solid but worth checking this vehicle's history carefully.

⚠️ About 1 in 12 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.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 1.9 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 428 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

What tends to go wrong

Across 428 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 24.4%

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 14.7%

Headlamp at least one does not illuminate on dipped beam · Exhaust slightly deteriorated

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

Exhaust & emissions 12.4%

Exhaust is leaking and excessively noisey · Exhaust is leaking but is not excessively noisey

Brake wear 11.3%

Rear Brake lever has inadequate reserve travel · Roller brake test The less effective brake control does not achieve an efficiency of 25%. · Rear Brake lever is bent but brake can still be readily applied · …

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

Suspension & steering 9.6%

Steering headbearing has slight free play · Steering headbearing has excessive free play · Rear shock absorber has a slightly reduced damping effect · …

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

Mileage Distribution

Most 2003 Sym Jet vehicles sit in the blue band. If the vehicle you're looking at is outside it, it's either unusually low or high mileage for its age.

12,580

typical

8,677

low mileage

17,962

high mileage

Half of all 2003 Sym Jet vehicles fall between 8,677 and 17,962 miles.

Is the mileage you're seeing normal?

✓ Under 8,677 miles — lower than most. Could be great, or could be a vehicle that rarely moved. Check test frequency and mileage progression in the MOT history.

✓ 8,677–17,962 miles — normal for age. This is where most 2003 Sym Jets sit.

⚠ Over 24,248 miles — higher than typical. Not necessarily a problem, but check service history and look out for advisory build-up on tyres and brakes.

2003 Sym Jet — Still on the Road

Numbers are thinning — 17% of 2003 Sym Jets are still active.

Numbers are declining — 10 vehicles still getting MOTs in 2021 (17% of peak).

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2014–2021.
* The 2020 dip reflects the government's COVID-19 MOT exemption, which allowed certificates to be extended by six months — fewer tests were conducted that year.
