Alvis TC 108 1956–1958 car dimensions: 4700 mm long, 1680 mm wide and 1330 mm high.
The cabin is a traditional British grand touring setup with leather seats and wood accents. Instruments are grouped on the dashboard, often with chrome rims. Rear seats are small and occasional, with limited legroom, as style takes priority over rear passenger space. No modern driver aids are fitted.
Boot space is modest and suited to luggage or shopping. Rear seats can be lifted out to create additional trimmed storage.
The cabin uses finest quality leather upholstery on all seats. Front bucket seats adjust separately for reach and rake. A modern dashboard holds a full set of instruments. A Smith's air-conditioning unit comes as standard. Floors are heavily carpeted over felt. Graber versions offer high-quality trim with occasional rear seats that lift out for extra luggage space.

The car runs on petrol fed by twin SU carburettors from a rear-mounted 14.5 gallon tank that includes a one gallon reserve switched from the dash. No specific consumption figures appear in period maker material for this model.
The traditional wooden-framed body construction requires attention to joints and panels over time.
Safety equipment centres on Lockheed hydraulic two-leading-shoe drum brakes all round with separate handbrake linkage to the rear wheels. No crash-test results are recorded. Suspension uses independent front wishbones with coils and a live rear axle on leaf springs for roadholding suited to grand touring.
