What the Mercedes-Benz 420 sticker says about fuel
Fuel economy is a legally required block on every Monroney label — city, highway and combined figures plus the estimated annual fuel bill. These are the EPA numbers on file for the 420, latest tested year 1991:
The label also prints an estimated $5,150 a year in fuel at 15,000 miles, and 615 g/mi of CO₂. EPA files the 420 under Midsize Cars, which is the class it gets compared against on the sticker.
How the 420's sticker figure changed
Combined MPG printed on the label, model year by model year — 1986 to 1991. Worth checking before you compare a 420 sticker from one year with another:
The figure has stayed broadly flat across the span. EPA revised its testing method in 2008, which shifts figures printed before and after that year.

Where to find the VIN on a Mercedes-Benz 420
- WindshieldLower-left corner, driver's side, readable from outside without opening anything.
- Door jambOn the driver's door frame of every 420, next to the tyre-pressure and build-date plate.
- DocumentsRegistration, title and insurance card — on a Mercedes-Benz 420 all three must show the same number.
All four must match. A Mercedes-Benz 420 whose windshield plate disagrees with the door jamb has either had a panel replaced or a tampered identity — check the paperwork before any money changes hands.
