A rare unraced 1994 Ferrari 333 SP is set to cross the block at RM Sotheby’s on September 9.

The lot is expected to sell for around $3.3m-3.9m at the sale at the marque’s headquarters in Maranello, Italy titled “Ferrari – Leggenda et Passione”.

The Ferrari 330 SP was one of the top racers of its era 

It’s one of 40 333 SPs built for competition in the (now defunct) IMSA GTP series during the early 1990s.

This represented Ferrari’s return to racing after two decades, during which time it focused on building road cars.

The 333 SP was a roaring success, winning a very respectable 56 out of 144 races between 1994 and 2001.

The present specimen, chassis #6, was ordered by a buyer who was unable to pay when it was ready to be delivered.

Over the years it changed hands between a series of in-the-know collectors and was driven sparingly.

This is strictly one for the track. The 333 SP was legendary for its ferocious speed and power.  

There’s also a jaw-dropping 1969 Ferrari 365 GTB/4, the only known road-going alloy example.

The lot was recently discovered in a barn in Japan and remains in original condition, untouched since the late-1970s.

The model originally belonged to Luciano Conti, a friend of company founder Enzo Ferrari. It was shipped to Japan in 1971.

It’s offered with a valuation of up to $2.1m.
