W126

The 420SE was the short-wheelbase W126 S-Class variant using Mercedes-Benz’s 4.2-liter V8, appearing in non-U.S. market references for 1990. It shared the same W126-era 420 mechanical package as the 420SEL but was not a U.S.-market offering. The available catalog context also shows a 1991 reference under the spaced name 420 SE, but the exact relationship between those entries is not fully verifiable from the provided data.
