Almost everything!
It was a very cheap car made of a fiberglass body attached to a very simple welded pipes chassis, with a Triumph engine.
The car was very unstable, seriously dangerous, unreliable, and very badly built.
My boss had a Sussita in 1969 and I agree that it was made by amateurs. But purchasing Israeli-made products was considered very patriotic. Just after my Boss bought it, he took it back to the Dealership in Haifa because the drive shaft rubbed on the chassis. The Dealer said they all do it and as he waited, the shop adjusted it with hammer blows.
