My friend had a cerbera for about 2 weeks last year it had 1 previous owner and only 19000 miles on it
Week one had a starting problem with the electrics, the afformentioned leaks and the back light filled up with water
Week two something major let go in the engine (not sure what) and it smashed itself to pieces
The garage gave him a full refund and he bought a 911 intead
The short time it was working though it was an absolute monster
