1970 Lambretta Grand Prix 0.1L Petrol · RMA 63H

The most recent MOT on 1 October 2025 recorded a pass, but it was accompanied by a failure for the rear brake pedal having insufficient reserve travel. Earlier failures were limited to a headlamp main‑beam fault in 2023 and an advisory about slightly notchy steering movement in 2014. Apart from those isolated items the majority of tests have passed without recorded defects, indicating that the vehicle’s overall maintenance record has been reasonably stable, with only occasional minor faults that have been addressed. With a recorded mileage of just 1,117 mi over 56 years the car averages roughly twenty miles per annum, a usage pattern that points to long periods of storage rather than regular driving. Such low mileage reduces wear on engine and transmission components, but it also means that many parts that rely on movement – rubber seals, suspension bushings, brake hoses and tyre sidewalls – may have deteriorated from age and lack of use. The very low annual run‑off suggests that any wear that does exist will be concentrated in components that have been idle for decades rather than from cumulative mileage. Prospective buyers should give particular attention to the rear brake system. Verify that the brake pedal now offers the full travel required by regulation and feel for any sponginess or binding when the pedal is depressed; listen for any clunk or uneven pull that could indicate worn push‑rod bushings or a failing master cylinder. Inspect the rear brake shoes or pads for glazing, corrosion or uneven wear, and check that the hand‑brake mechanism engages firmly. The headlamp main‑beam circuit should be tested for both low‑ and high‑beam operation, ensuring the bulb, wiring loom and relay are intact, as a fault here can be a symptom of corroded connectors in a car that has sat for long periods. Given the vehicle’s age and minimal use, a thorough visual and tactile survey is essential. Examine all tyre sidewalls for cracking, dry rot or hardening of the rubber, and confirm that tread depth is adequate despite the low mileage. Look for rust on the chassis, suspension arms, brake lines and exhaust system, paying special attention to areas where water may have pooled during storage. Test the 12 V battery voltage and load, as lead‑acid cells can sulphate and lose capacity when left idle for years; a weak battery may also affect electronic lighting and ignition. Finally, check that coolant, brake fluid and gear oil have been changed within the recommended calendar intervals, and inspect seals and gaskets for leaks or brittleness that can develop even without mileage. A careful pre‑purchase inspection covering these points will reveal whether the car’s age‑related deterioration has been mitigated or if further remedial work will be required.
