There are a half dozen Jaguars scheduled to go on the block during the Russo & Steele Auction in January, part of the huge auction and concours week in the Phoenix and Scottsdale area. Four of the Jags are E-Types.
Dennis Eynon has arranged for JCCA members to receive a 50% discount on bidders' passes for the auction. Here's a link to the discount page.
