At Autowerke Engines every M54B25 is a real used engine from our yard in Hamburg. The photos on each listing show the actual engine, not a stock picture. The yard checks the code, records what is bolted on, and seals the openings before the engine is offered. Each listing shows the year, the mileage and the price, so you can compare units side by side.
