$250,000 is a heck of a lot of money, and can get you a heck of a lot of car. At your local Ferrari dealer alone, that'd be more than enough to put you into a Portofino convertible, about enough to take home a 488 GTB, and almost enough for a GTC4 Lusso T. But if we had that kind of scratch, there's another Prancing Horse (of sorts) that we'd be more tempted to invest in.

It's a 1992 Spice Ferrari SE 92C – a racing prototype built on Group C building blocks for the IMSA GTP Championship.

The project was undertaken not by the factory in Maranello, but by British businessman and racing driver Gordon Spice, (after Ford withdrew its support from the team). But it appears to have had Ferrari's blessing (four years after Enzo's passing), and at any rate packs the beating heart of an F355 – the precursor to today's 488. The 3.5-liter, 40-valve, naturally aspirated V8 produced 375 horsepower in road-going guise, but was upgraded with a hundred more horses to 475 hp for this competition application. And it's painted in the same shade of Rosso Barchetta that the Prancing Horse marque championed in its early days.

Though it didn't achieve any major victories to speak of, we bet it'd still be one heck of a track toy. In fact it's said to have been a regular at Ferrari club events, though it's only been used lightly out on the track since it was retired from active duty.

With a new fuel cell, clutch, and extra set of BBS alloys, this obscure chapter in Ferrari's extensive racing history is coming up for auction as part of RM Sotheby's sale in Scottsdale next month. The auctioneer expects it to bring in between $250,000 and $300,000. (Photos by Erik Fuller for RM Sotheby's.)
