"You'll Go Far In a Datsun". Lol.
Not IIRC, or ISTR, IRWUA; [recollect with unfailing accuracy]
Here in the 70's & 80's, gas crisis and first mass import of small Japanese cars, license plate frames began getting text. The two most seen were "Do It In A Datsun" & "Try It In a Toyota". They weren't overtly suggestive, other than to us having well developed social intent.
But my attention was focused on a sweet thing driving a Fiat 850 Spyder, even smaller. I made her a frame with 3D stick on letters, reading "Forget It In A Fiat".
