Check out this commercial:

Scroll down a tiny bit; link is on the right.
It is billed as a 1957 Dodge commercial, but if you listen to it, it really is for '58. Oh well!
That's an interesting site. I'll have to view a few of those commercials...
My dad had a '56 and '60 Dodges when we were kids; slick cars!!
