BMW E9 1971–1975 car dimensions: 4660 mm long, 1700 mm wide and 1360 mm high. Unladen weight is 1,380 kg. Braked towing is 1,300 kg.
The cabin has a wood-trimmed dashboard with clear analogue gauges and well-padded seats available in vinyl, cloth or optional leather. Rear electric windows are standard while front ones are optional. Air conditioning is an optional extra. Visibility is excellent thanks to large glass areas. No electronic driver aids are fitted.

Payload is 390 kg. Braked towing capacity is 1300 kg and unbraked is 650 kg. The car is a luxury grand tourer rather than a work vehicle.
The cabin has a driver-focused layout with a broad woodgrain dashboard and clear round analogue gauges. Front seats are well-padded and reclining, trimmed in vinyl or optional leather. Sound insulation is good for the period. Rear seats offer decent space for a coupe. Optional air conditioning and sunroof are available along with power windows on some cars.

The car runs on petrol. Spec sheets list combined fuel use at 11.2 l/100 km and extra-urban at 8.5 l/100 km. The tank holds 72 litres.
The M30 engine needs careful cooling system checks as overheating is a known weak point that can warp the alloy head. Drivetrain parts interchange with period BMW six-cylinder models and remain available. No fixed service intervals appear in period records.
Safety kit includes ventilated disc brakes at all four wheels with servo assist, three-point belts for front and rear seats, crumple zones front and rear, padded interior surfaces and safety glass.
Body corrosion is the main ownership concern. Check fenders, rockers, floors, shock towers and sunroof drains regularly. Structural repairs can be extensive if rust has progressed.
