An acquaintance of mine is attempting to match up the cars used in the "Worthless" song in the movie The Brave Little Toaster to real-life models. While this at first may seem an exercise in futility, given how generic most of the cars in the movie look, at least a few of the vehicles have some details which correspond to real cars. The only problem is that they claim the hearse used in the scene is a 1973 Rolls Royce Silver Shadow. Now, I understand that Rolls-Royces were/are offered in the US for many, many years but were they sold in hearse models here? Were there any US coachbuilders that made hearses out of foreign luxury cars as oppose to domestic ones? I know this is just a cartoon movie but I am genuinely curious and I've Googled trying to find US Rolls-Royce hearse coachbuilders and come up totally empty.

If none exist, I suppose it could be an import, as in, imported as a hearse, but this seems like a lot of money for a funeral home to throw at a hearse when they could use a comparatively cheaper domestic model. So could someone explain to me the likelihood of a Rolls-Royce hearse in the US and who would've made it?
