If that doesn't scream, "good old-fashioned luxury," I don't know what does!
One more year to go before Cad ditched their old flathead V8 and stuck in an OHV.
The 48s did have the flathead too. I have a 48 series 75 in my garage and I can tell you without a shadow of a doubt its got a flathead. That said I have no intentions of keeping that way when I do get to working on the car in a few years.
