A rare and coveted 1955 Ferrari will hit the auction block tomorrow (May 21) at the Concorso d'Eleganza Villa d'Este auction in Como, Italy, RM Auctions announced. The luxury sportscar is the final of ten 375 MM Berlinettas built, and is also the last even-numbered car built by Pininfarina. The car is estimated to sell between $4.5 and $6 million dollars.

The vehicle comes with several Ferrari styling cues that were to be found on future models, including front fender vents (which would be widely copied) and a lower grill with a flatter top. After 30 years of continuous ownership it was restored in 2004 by Wayne Obry and immediately entered in the 54th Pebble Beach Concours d'Elegance in Monterey, California in Class M-2 Ferrari Speciale, which it won, scoring 100 points.

In addition, it also features rear window louvers, which would appear in the 250 GT TdF model, and headlights without bezels, which were continued on other models. However, it does not have exaggerated rear-fender treatment common on similar Ferraris.

Also included in the auction are a 1937 Bugatti Type 57SC Atalante Coupé and a 1915 Rolls-Royce 40/50 Silver Ghost Limousine.
