RM Auctions is ready to auction off a very rare 1935 Mercedes-Benz 500 K Roadster by Sindelfingen at Monterey tomorrow. It's expected to bring in around $4 to $5 million. At its initial debut at the 1935 Berlin Motor Show, the Roadster had a metallic green finish, but now it's finished in rich red highlighted by chrome wheels, whitewall tires, dual rear spares, a pair of windshield post-mounted spotlights, chrome outside exhaust head pipes and chrome body accent moldings.

Both front and rear fenders present a glimpse of the rugged and all-purpose chassis frame and suspension. The interior is upholstered in tan leather with a matching tan single layer cloth top. The top folds nearly flat with the rear deck under a matching trunk cover. According to the auction house, the vehicle is "magnificently designed, constructed, and maintained by a succession of owners...it's had constant attention to any need with a lifetime of professional maintenance."
