The car runs on petrol. A 1954 road test of a related saloon recorded 20.6 miles per imperial gallon. The tank holds about 14.3 imperial gallons or 65 litres.
Servicing centres on regular chassis lubrication. There are 19 grease points that require attention every 1000 miles. Engine access is helped by detachable side panels and a spark-plug cover. The design favours long intervals between major overhauls.
Braking uses Lockheed hydraulic drums of 11-inch diameter. Standard lighting includes a paired front fog lamp and matching driving lamp. No crash-test ratings appear in the record. One Graber example notes rear seat belts.
The car is built for durability with a welded box-section chassis and independent front suspension. Parts support comes through the owners club. Graber bodies are bespoke coachwork on the standard chassis, so body repairs need specialist attention.
