Am trying to trade my 2009 Cayenne Turbo S (my first Porsche) for a 2010 C4S Cabriolet. Have found one with everything I want including PDK except it does not have Sport Chrono Package Plus. I have just spent over an hour searching and reading the threads on the subject and opinion runs high on both sides as to whether you must have this option. On my Cayenne I have 3 modes - Normal, Comfort and Sport. In Sport suspension tighter, etc and shift points higher, much faster acceleration. So my questions are without Sport Chrono in the C4S do I only have one mode, "normal" or is there a sport mode and I lack only sport plus. If there is a sport mode what changes when it is activated. Thanks, can't find exact answer searching and have to decide on this vehicle or go search for another, unfortunately there are only about fifty 2010 C4S Cabs left in US and I can get a nice discount, so want to find one if I can.
