Why do Chevrolet commercials say CHEVY?
 

Why don't Cadillac commercials say CADDY?

My guess is to retain the distinguished and luxurious sound of "Cadillac"!

Visit your local Caddy dealer for yearend deals hahaha

nice caddy bro!

Because "Chevy" is just iconic. End of story.

Chevy is an abbreviation that started down south and traveled north over time. It is now accepted to mean Chevrolet, much like "rims" has now replaced the correct description of wheels and "passenger/driver" are terms now used to describe where on a vehicle a part is instead of the century old industry standard of Left and Right.

Not proper to use it in TV commercials they don't say Caddy in commercials

Caddy
 

There are 159 ads listing “Caddy Dealer” in the 1960’s. 285 in the 1970’s

as for left / right or driver / passenger use, i totally agree with using driver / passenger because most people dont know if you are to decide left or right from sitting in the car or standing in front of it looking at it. i have dealt with this for over 40 years in my automotive business. it didnt take long to realize the need to question them on which side they actually meant. and for that matter most people dont know how to determine a right or left swing door. which in my construction business we always have to go over every single door to get it right.

And that is why this has become so pervasive as to become the new "normal". We have allowed the usage of incorrect words to describe things. When I was growing up, I was taught the standards and use them. My 29 yr old son knows these standards as well, because he was taught them. I still attempt to educate people of the correct way to describe their concerns on their vehicles when they ask for my help with a problem.
