Although the Model L Cadillac Limousine had a planetary transmission and 5" x 5" bore and stroke like the single cylinder Cadillac Runabout, the two models were entirely opposite in concept.
The single cylinder was a horseless carriage for the masses, the Model L a Nabob's throne-on-wheels.
Whether due to the Alanson Brush patent squabble, acute marketing perception, or both; Cadillac came up with a four cylinder design which met the expectations of customers who wanted just a bit more than the best one cylinder car could offer — an inexpensive, easily maintained, long lasting, precision built car — a "single cylinder Cadillac with four cylinders" — the Model G.
Serial numbers on plate on rear of body or on dash (with engine number).
Engine numbers were stamped on top surface of crankcase — in front of and to the left of number one (front) cylinder.
Model G engine numbers: 30003-30425 (1907), 30426-30500 (1907-1908).
