A very basic Z4 would be about $47,000 for a 2011 Z4. Like many other cars you can buy different "editions" of a car. In the BMW Z4 there is a Z4 sDrive30i ($47,000+), Z4 sDrive35i ($53,000+),Z4 sDrive35is ($62,000+). The same goes with the Ferrari. I can't give you the exact differences but it would be $100,000+
