Okay–here some others:
The Porter Stanhope–The only perfect automobile (Perhaps a slight exaggeration?)
Ford–Don’t experiment. Just buy a Ford (Circa 1905, that might actually have been a good idea, given how many makes existed for such a short period of time.)
KisselKar–The all-year car (You don’t want one of those cars that you can only drive in September!)
Chevrolet–For economical transportation (Perhaps one of the few reasonably honest slogans.)
Graham–There’s something about a Graham (Do you smell something?)
Hupmobile–Step up with Hupp–and also–Hupp has always built a good car
Plymouth–Buy wisely, buy Plymouth (But–the Ford folks told me that would be an experiment!)
Crosley–A fine car (As long as you don’t require an engine that lasts more than 15k miles or so.)
Nash–You’ll be ahead with Nash (I’m confused. The Pilot folks already told me that their product was “the car ahead”!)
Jeep–All over America, people are saying, “That’s the car for me”. (Or not)
Studebaker–First by far with a post-war car! (It was the first totally new design following WW2)
Tucker–The first completely new car in fifty years. (Very true, but…)
Chevrolet–Has the whole town talking (But…what are they saying?)
Imp–The little car with the big future (Ummm…no. This one vanished within a few months of its introduction.)
Packard–Packard’s the one for '51! (…and for just a few more years after that.)
Ford–The ablest car on the road for '52! (So–I shouldn’t even consider a Mercury or a Lincoln?)
Corvair–With the engine in the rear, where it belongs! (So–the Impala has its engine in the wrong location?)
Vega–The little car that grows on you (Like warts?)
