The Fairfield County Concours d’Elegance in Westport, Connecticut, is celebrating the 50th anniversary of the Jaguar E-type by launching a search for two special cars: The privately owned car with the lowest chassis serial number and the privately owned car that is the longest privately held single-owner E-type. The search is restricted to the 48 contiguous states.

If you think your Jag might qualify for one of these honors, simply surf on over to the concours’ online submission form. There, you’ll be asked to submit information and photographs (exterior three-quarter front and side views, one each) of your car.  Both of the winning vehicles will be featured at this year’s event. The Fairfield County Concours conducted a similar event in 2009, when it launched a nationwide search for significant Pontiacs for its display.

“We have always had several remarkable E-type Jaguars in our show field each year,” said Bill Scheffler, CEO and co-founder of the Fairfield County Concours.  “To celebrate the 50th year since its introduction, we decided to make the car one of our featured judging classes for 2011. Adding the search for two special E-types will increase the interest in this very special car at our event.”

More than 200 vehicles spanning the past century will be on display at this year’s concours, scheduled for September 17 and 18 at the Fairfield County Hunt Club. The concours, now in its eighth year, is by invitation only; if you’d like to have a car considered, you can fill out the same online submission form. The deadline for submissions is June 15; those who wait until the deadline may find that the classes are already filled, so act now if you’d like your car to be considered.
