&lt;p>Rarer still&amp;nbsp;is this 1955 Jaguar D-Type campaigned by the privateer race team Ecurie Ecosse and driven to victory in the 1956 24 Hours of Le Mans by Ron Flockhart and Ninian Sanderson. It is the first series production D-Type and the first to be designated such. It is the only Le Mans-winning C- or D-Type that has survived intact and remained essentially original to its winning form. Which is why it is expected to sell for &lt;strong>$20-to-$25-million&lt;/strong> (USD) at RM Sotheby&amp;rsquo;s.&lt;/p>
