1983 Land Rover 109 — MOT failures & pass rate
Across 262 MOT tests, the 1983 Land Rover 109 recorded a 78.2% pass rate. That is 2.6 percentage points worse than all cars of a similar age, which fail at 19.1%. Failures cluster in lighting & signalling, visibility and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 15.7% of all tests — 6.5 points clear of visibility, so it is the first thing to check.
At component level the recurring items are position lamp, washers and non catalyst emissions — position lamp alone was recorded 22 times.
Mileage is the strongest signal on the record: 18.4% of 0-30k cars fail, rising to 27.6% once past 60-90k.
Advisories point at the next bill rather than this one: emissions & environmental was flagged on 22.9% of tests without failing them.
The trend is improving — the fail rate fell from 25.8% in 2021 to 16.1% in 2024, as the worst-kept examples leave the fleet.

What to check before buying a 1983 109
On a 1983 109, lighting & signalling is what the MOT record says goes wrong most — it appeared in 15.7% of tests. Check these areas before you commit.
- Lighting & signalling (15.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (9.2% 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.
- Brakes (9.2% 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.
