Any car with the Rolls-Royce emblem on it and a rare prototype from 85 years ago--either one could serve as the quintessential centerpiece of a distinguished car collection. Roll both into one, therefore, and you have an ultimate collector's item that should make all your car-collecting pals green with envy.

The 1926 Experimental Phantom 1 Continental (10EX) has been called the first sports car developed by Rolls-Royce. In designing it, Rolls sought to implement a lighter, 'torpedo coachwork' body style to give it a faster ride. During its storied history, the model nicknamed the 'CJ Sports Car', after Rolls managing director of the time D. Claude Johnson, was loaned out to Laurence of Arabia for continental touring.

The 10EX will be the headliner of seven Rolls models being auctioned of by RM Auctions at the Salon Privé luxury car show on June 23. It is expected to sell between £400,000-£800,000 ($650,000 to $1.3 million).

The classic Rolls prototype will be one of the most exciting cars on the block, but there will be plenty of other interesting buys. Max Girardo, Managing Director of RM Europe describes in RM's press release: "We have pulled together a collection of very interesting and significant collector cars and motorcycles which represent some of the finest and most significant vehicles produced in England during the pre- and post-war periods."

Other cars being auctioned by RM include a 1939 Aston Martin 2-Litre Speed Model one-off race car, 1929 Bentley Speed Six "Le Mans" VDP Tourer, and 1955 Bentley R Type Continental Fastback. RM will also be selling off two-wheeled classics like the 1939 Brough Superior 11.50.

The collection will be previewed on June 22 between 11 a.m. and 9 p.m. GMT and June 23 from 9 a.m. to 5 p.m. The auction will commence at 5 p.m.
