Should I check the MOT history before buying a 1981 Lambretta Gp150?

The 1981 Lambretta GP150 passes its MOT first time at 88.3%, which is a solid 8.3 points above the UK average of 80%, suggesting these scooters are generally well-maintained by their owners. Dangerous defects are rare at 6.7%, so safety concerns aren't a significant issue with this model.

Most of these machines show remarkably low mileage—a median of just 1,248 miles despite being over 40 years old—which tells you they're cherished classics rather than daily riders, and this low usage partly explains the strong pass rate. Each vehicle typically racks up just over one failure and 1.8 advisories per test, indicating minor wear rather than structural problems; if you're considering one, check the service history and test-ride it thoroughly to ensure the engine and gearbox feel smooth.
