My favorite of the cars of this type is the '48 Pontiac "Chieftain".

It had the "torpedo-back" rear styling and usually came with that super classy sun visor that was popular in that era.

It could be had with either a flathead six or an equally flat-headed straight eight. Not exactly the top choices of the performance-minded set, but that engine was so smooth-running at idle that a driver sometimes thought his engine had died,so he hit the starter. That produced an impressive noise.

Now, that was embarrassing! I know, because I had a Beautiful '51 Chieftain
Club Coupe and I made that that cool move more than once.

Google one and let me know what you think!
