Two schools of thought here. GM never planned for this to be a running car. It was simply a study in "modern" (for the time) town car design, a pushmobile, a reminder of a bygone era. Personally, I would have left it as it was conceived in 1956, i.e. a piece of 3D art (as Bruce says), to be exhibited in an art museum. It's like the 1961 Pinin Farina "Jacqueline" coupe that was purported to have been built on a 1959 Eldorado Brougham chassis; it too was just a pushmobile until someone grafted it (at great expense) onto the well-worn chassis of a 1960 Eldorado convertible with an even older 1959 motor. Shame ! Who would want to graft arms onto the statue of Venus de Milo?
