Flat battery.

Yep definitely sounds like a dead battery.  Happened in our 156 a few months ago - I've never had a battery die in a modern car.  No warning at all, in all my old cars you had plenty of warning from slow cranking but on the 156 it just didn't start one day with the same symptoms - crazy dash lights and clicking.  I also thought something more dire had happened.

100% dead battery.  Had the same scary, no warning failure on my 156GTA that had me thinking all sorts of scary thoughts watching the radio reset itstelf, the odometer zero iteself and the instruments lights flciker on/off.
