"It's one of the Ferraris with the most victories in the constructor's history, so it's a very important car in the history of motor racing," Vincent Luzuy, from the Sotheby's branch dealing with luxury car sales, told AFP.
Designed by Rory Byrne and Ross Brawn, the F2003-GA featured a longer wheelbase to improve aerodynamics, he explained.
The model was brought in at the Spanish Grand Prix, the fifth race of the 2003 season. Chassis 229 is by far the most successful of the six F2003-GAs that were built.
Schumacher drove it to victory in Spain and also won the Austrian, Canadian, Italian and US Grands Prix in the car.
He also claimed pole position in Spain, Austria and Italy in the vehicle, and the fastest laps in Austria, Italy and the United States.
