1936 Alvis Speed 25 3.8L Petrol · RN 5387

The most recent MOT test for this Alvis Speed 25 was passed on 22 August 2024, following a significant failure earlier that year. The maintenance trend appears somewhat reactive, characterized by critical failures in the braking system that required rectification to achieve compliance. While the vehicle is currently considered roadworthy, the history of dangerous and major defects related to both service and parking brake efficiency suggests that the braking system is a high-maintenance area that requires consistent monitoring. The progression from major braking failures in 2022 and early 2024 to a pass in late 2024 indicates that repairs have been made, but the underlying reliability of these systems remains a point of concern for long-term ownership. With a recorded mileage of 48,064 over approximately 90 years, the vehicle has covered an average of only 534 miles per year. This extremely low annual usage is typical for a classic vehicle kept for occasional enthusiast use or exhibition. While this low mileage suggests minimal wear on the engine, gearbox, and drivetrain, it introduces specific mechanical risks associated with long periods of standing. Infrequent use can lead to the degradation of rubber components, the settling of lubricants, and the development of internal corrosion within the braking system and engine, which are not directly correlated to the distance travelled. Prospective buyers should pay particular attention to the braking system and the recent advisory regarding the nearside rear wheel bearing. During a test drive, listen for any rhythmic grinding or humming noises from the rear, which would indicate the bearing play is progressing toward failure. Test the service brakes for consistency; any shuddering, pulling to one side, or excessive pedal travel could indicate unevenly worn discs or binding calipers. Given the previous history of parking brake inefficiency and lever ratchet issues, the handbrake must be tested thoroughly to ensure it holds firmly on an incline and operates smoothly without slipping. Due to the vehicle's age and low usage profile, a thorough physical inspection of age-related degradation is essential. Closely examine the tyres for sidewall perishing or cracking, as rubber components often fail due to age long before the tread is depleted. Check the chassis and suspension mounting points for signs of corrosion or surface rust that may have accumulated during storage. It is also vital to confirm that time-based maintenance has been performed, specifically regarding the replacement of brake fluid and engine oil, as these fluids degrade chemically over time regardless of mileage. Finally, inspect the condition of the shock absorber bushes and other suspension bushings to ensure they have not perished or become excessively worn.
