Here's another UK print ad for an MG product, this time for the beloved Midget. I had a high school classmate that drove a Midget identical to the one in this ad (except for the right hand drive aspect). It's been years since I've ridden in a Midget, but I distinctly remember how sobering it was to view the underside of the trailer of an 18-wheel rig from that car.
MG used the "Your mother wouldn't like it" slogan for the MGB as well although the young lady in the MGB ad seemed to be suffering from a lack upper undergarment. I'm sure my mother wouldn't like that.
