Mazda5 Print Ad in Real Simple Magazine

I stumbled across a Mazda5 advert (headline: slip into something sexier.) in the August edition of the Real Simple magazine. I was completely shocked at the spelling and sentence structure used in the ad. Does Grey have a writer? Did the writer bother to copy check the ad? In the sub-head the word leather is spelled "leathrer". How on earth did client allow this to go to print and more importantly, how on earth did Grey allow this to leave their agency? There are basic grammar errors in the body copy - one of which include the use of the (.) in the acronym S.A. - as per the English Oxford dictionary the correct way of "spelling" this is, SA - a basic that any writer should know. Sentence structure is appalling, broken and completely sloppy. It appears to me that the writer who wrote this piece should not be a writer at all. Basic mistakes such as these do not increase the value of a premium brand - in fact, it makes the brand seem like a joke. And all of this comes from a writer, himself. Absolutely shocking. Mazda should think twice before briefing anything else to Grey Advertising.
