Porsche marketing thinks that this marketing strategy is a good thing. Personally, I think this is kiddy play.
C'mon, we're talking about a car for 60 grand or more, not a TV soap opera where people are curiously awaiting the next episode to see if the mother married her stepbrother who is actually her father and her brother's gay lover...

I love Porsche cars but I think that Porsche advertisement and marketing is very bad. I bought 6 cars over the past 8 years and I didn't like one single Porsche ad. They are boring, they usually don't have much to do with the car itself. If Porsche thinks that this kind of marketing and advertisement is good and gets them customers. Fine. But I can tell them for sure that I didn't buy ONE SINGLE Porsche because of the ads I saw. On the contrary, they usually left a bad taste on my tongue.
The current Cayman teaser is similar to the Cayenne teaser. Horrible. C'mon, we're adults, people who spend a lot of hard earned money for a car. If they want to sell us a product, they better show it to us from the start. The teaser does only one thing in my opinion: it takes away a lot of the excitement of the car itself.
If people like me and you don't like such teasers, why does Porsche do this? Well: they sold so many cars in the past and their logic seems to be that if the customers buy the products, they're happy with how they're advertised. Well, maybe the products are just THAT good that even bad advertisement and marketing can't hurt them.
