Seven-figure cars highlight day one of RM's Monterey auction

RM Auctions is one of several houses holding auctions during the Monterey weekend, and Friday night's festivities got quite pricey. Seven-figure vehicles were not at all uncommon during the first day of the two-day event, with the 1953 Ferrari 375 MM Spider, seen above, crossing the block for $9,075,000.

Other big earners included a pair of rare Ferraris, a 1950 166 MM Barchetta and a 1955 750 Monza Spider, which took $3,080,000 and $4,070,000, respectively. Outside of the red Italians, a 1939 Mercedes-Benz 540K Special captured $7,480,000 while a stunning, color-appropriate 1955 Jaguar D-Type took $3,850,000. We've got images of these vehicles, and a few other stunning examples of last night's auction, in the gallery above.

Thought it seems impossible, tonight's auction is expected to see even more high-dollar action. The winner of the 2012 Pebble Beach Concours, a 1928 Mercedes-Benz 680S Torpedo Roadster is expected to command over $10 million. Also crossing the block will be a car we reported on a few weeks back - a supremely rare 1967 Ferrari 275 GTB/4 NART Spyder. One of only 10 in the world, it's expected to take anywhere from $14 to $17 million when it hits the stage tonight.
