1956 Cadillac Eldorado by Brooks Stevens from The Bortz Auto Collection to be featured at the 2014 CCCA “2014 Grand Experience” at the Gilmore Car Museum campus in Hickory Corners, Michigan on Sunday June 1, 2014.

The Bortz Auto Collection was honored to receive a request to have its 1956 Cadillac Eldorado by Brooks Stevens be the featured car at the 2014 CCCA “2014 Grand Experience” at the Gilmore Car Museum. This concept car is one of two and was the one featured in 1956 throughout the European 1956 auto shows. It was also the headline grabber at several automobile shows in the United States, including the Madison Square Gardens annual car show.

This Cadillac/Lasalle themed event will take place at the CCCA Museum on the Gilmore Car Museum campus in Hickory Corners, Michigan, on Sunday, June 1, 2014, from 9:00 a.m. to 4:00 p.m. There will also be a grand classic for all CCCA full classics.

It is interesting to note that the Bortz Auto Collection was on exhibit for two years at the Gilmore campus museum building in the late 1990s.

The Cadillac die Valkyrie is rarely shown making it a very special event for car collectors and spectators who have not had an opportunity to see this most significant concept car design. One of the more significant design features is the enormous “V” bumper at the front of the car. This was done because Brooks Stevens, an international car designer, wanted to have the car tour in Europe as well as the U.S. He wanted to show off the fact that most American high end cars were V8 while the Europeans engines were either straight six or straight eight. Brooks Stevens was also famously known for painting many of his other concept cars in his signature black and white color scheme.

The 1956 Cadillac Eldorado designed by Brooks Stevens with a one off custom Spohn body for the auto shows of 1956 from the Bortz Auto Collection will be featured at this event.
