Maybe I'm wrong but it seems like Caymans are selling well simply because dealers are stocking lots of them (as opposed to Boxsters) and a big chunk of sales come from people buying what is on the lot. In other words, the dealers in my area seem to have lots and lots of Caymans but very few Boxsters sitting on the lot so maybe people are buying the Cayman "because it's there." This seems like a great (and sneaky) way for Porsche to sell the more expensive Cayman because they know some people want instant gratification and buy what's on the lot. Again, maybe I'm wrong.
