What car is this and what engine does it have, for one point
It´s a Bucci Special from Argentina and it has a Mercedes AMG V12 engine.
Yes perfect answer
A rear view:
Is it still "work-in-progress" or is it dead?
As far as I know only one car has been built. Production is intended but it surely is not easy to undertake.
My understanding is that the car was half finished when Clemar Bucci passed away.
Yes when Clemar Bucci died in January 2011 the car was unfinished, the project was followed by Pablo Bucci who is the grandson of Clemar's brother Roland.
