The Cayman looks like a 911 and the new Cayenne has roots with the 911 (according to Porsche marketing). Is this not the branding of all car manufactures? For me it is just a question of cost and image. For some or other reason (which I do not understand) the R8 has not gotten the sales volumes and place in the sports car "ranking" it should have. As you can see I have both a 911 turbo and a R8 and on pure quality and driving the R8 is the better car. The R8 masters the balancing act between daily "smooth" driving and track performance the best. But at the end it is like the stock market: the market is always right. As sad as it is the R8 as not become the brand icon Audi was hoping it would be.
