Mercedes-Benz W126 500 SEL M117 – Inspection and Repairs

The Mercedes-Benz W126 500 SEL is far more than a large luxury saloon: powered by the M117 V8, it is one of the marque’s most distinctive classics. On this example, we inspected the engine and valvetrain, repaired several electrical components, and addressed faults in the front suspension. This gallery shows the precision and attention to detail required to return such a special Mercedes to the refined performance expected of a 500 SEL.
