S370 CWS MOT History
Interpretation generated from the recorded test data above — not an official DVSA statement and not a substitute for an independent inspection.
5 MOT tests are recorded for this 1998 Mg Mgf (S370 CWS) between September 2021 and December 2025.
The record contains 3 passes and 2 failures.
The most recent test on 15 December 2025 was a pass, although the earlier record includes 2 failures that buyers may want to investigate.
Across all tests, the most frequently flagged areas are: Brakes (6 issues), Lighting (5 issues), Suspension (4 issues), Steering (1 issue). Repeated mentions in one area can indicate an ongoing pattern worth checking in person.
In total 13 advisory notices are recorded. Advisories flag items that passed but may need attention before the next test; they are not evidence of how well the vehicle has been serviced.
Recorded failure items include: “Offside Front Headlamp aim projected beam image is obviously incorrect (4.1.2 (c))”; “Offside Rear Wheel bearing has excessive play (5.1.3 (a) (i))”; “Nearside Front Headlamp aim projected beam image is obviously incorrect (4.1.2 (c))”.

Our Verdict
A low-mileage classic roadster that offers potential but currently shows a clear pattern of ongoing corrosion and suspension wear that requires immediate attention.
When inspecting this MGF, your absolute priority must be the brake system. The MOT history consistently flags corroded brake pipes across multiple locations (offside rear, nearside, and central) from 2021 through 2025. This is a common issue on these cars, and you should verify if the pipes have been replaced with copper lines or merely treated. Additionally, check the rear suspension geometry closely; the recent advisories for worn bushes and steering rack inner joints suggest the car may suffer from poor handling if not serviced.
Check the chassis for rust, which is the MGF's Achilles' heel, specifically around the rear wheel arches where corrosion was previously noted in 2022. Given the low mileage, ensure there is a documented history of the oil belt changes, as these are critical for the K-series engine regardless of mileage interval. Look for any signs of fluid leaks from the exhaust, as a minor leak has been noted in the past.
The 1.8L K-Series engine is relatively efficient for a roadster, typically yielding around 25-30 mpg depending on driving. As an older petrol vehicle, it falls into a lower tax band, though insurance groups vary significantly based on driver profile (typically between groups 20-25).
Maintenance costs can be higher than a modern hatchback as parts are increasingly specialty and often require specialist knowledge. You should budget an annual running cost of approximately £900-£1,200, covering fuel, tax, insurance, and routine servicing/maintenance.
Inspect the entire brake line length for corrosion. The MOT history shows a cycle of corroded pipes over four years, which suggests that surface repairs may not have been fully addressed. Also check the steering rack for play, as the nearside inner joint was flagged in the most recent 2025 test.
Pay close attention to the rear suspension bushes and track rod ends. The data shows multiple instances of worn components and play in ball joints. A test drive is essential to listen for knocks over bumps and check for uneven steering feel. Finally, check the headlamp alignment, as this vehicle has failed or been advised for incorrect aim in the past.
This 1998 MG MGF is a rare low-mileage example, having covered just 51,770 miles over nearly 28 years. While the low mileage suggests a well-preserved example, the MOT history reveals a persistent issue with brake pipe corrosion and suspension component wear-out. The vehicle has recently passed its MOT, but the recurring advisories indicate that maintenance-related structural issues need to be addressed to ensure long-term reliability.
The K-series engine is known for potential head gasket failure if not maintained correctly, and the chassis is prone to structural rust.

Historical fault & advisory patterns
Common Problems: MG MGF
Known issues reported by owners and MOT testers.
- Hydragas Suspension Leaks/Depressurisation(Moderate)
The unique interconnected fluid/gas suspension system can leak or lose pressure over time, leading to a harsh ride and low ground clearance.
- Head Gasket Failure(Serious)
Standard K-Series issue, exacerbated by the mid-engine layout and long coolant pipes to the front radiator.
