TheModel L 2-door Touring sold for $3750 and the 2-door Limousine sold for $5000. Calendar year sales and production are unknown, probably very limited. Model year sales are the same. Serial numbers were on a plate on the rear of the body or on the dash (with the engine number). Engine numbers were stamped on top surface of the crankcase – in front of and to the left of the number one (front) cylinder.
The Model L was introduced on January, 1906. It was based on 1905 Model D.
