Beautiful Cadillac Expressive concept car escapes GM's vault

Well this is a strange (though lovely) one. We're used to automakers showing full-scale, highly detailed concept cars to the public. After all, they cost a lot of money to create. But here we have the Cadillac Expressive, a concept coupe that was created a number of years ago, but has been hidden away in GM's "Vault" until now. It was pulled out of mothballs for the Eyes on Design show at Ford House near Detroit.
