Subaru WRX STi is an impressive car. In fact, it is so impressive that it outrunned a twice more expensive Porsche Cayman to ¼ of a mile. However, when measured at the one mile checkpoint, the Porsche was fast. It is clear, the Cayman is a high-speed vehicle while the WRX STI can hold its breath to 130 mph. Nevertheless, you could buy almost two Subarus for the price of one Cayman.
