1 of 129 Ferrari Monza SP1 crops up on sale

A pristine Ferrari Monza SP1 single-seater will cross the auction block in the United States in late March. Believed to be one out of just 129 examples in existence, it will likely hit the upper seven digits.

When it was new, the SP1 started from U.S. $3,000,000 and was only available to select Ferrari clients. The Italian automaker made a total of 499 Monza cars, but most of the buyers opted for the two-seat version.

In contrast, this example only seats the driver. It was made five years ago and has a low 140 km (87 miles) on the odometer.
