Help identifying a car

I saw a strange car on the way home today – it was in the general shape of an old car, like an old Cadillac or something, but with a modernized look. It was clearly new-ish. It was silver. I only saw it from the back. The license plate was inlayed at an angle into the left side of the trunk, but that could have been custom I guess. Does anyone have any idea would this could be? Thanks.
