With five upcoming auctions in Monterey, several multi-million dollar cars are on offer and we have the five greatest in this preview. The first is this unique 1949 Delahaye 175 S we saw in 2006. It is the most dramatic roadster by Saoutchik and RM has a presale estimate of 4~6 million USD.

RM also have two Ferraris which might fetch the top sale of the weekend. Both the Ferrari 250 Testa Rossa and Ferrari 375 MM Berlinetta are some of the very best sports racers from Maranello.

Bonmhams has an impressive Porsche collection and is going to offer the Porsche 917 Interserie Spyder we featured earlier. Lastly if we had to pick any car, the Alfa Romeo 8C 2300 Monza from Gooding & Company should be the top sale of the week.
