Alfa's large executive sedan was sold in South Africa in small numbers in the early 2000s, mostly with the 3.0 V6. It fought the 5 Series and E-Class with little success and depreciated faster than almost anything in its class. That makes surviving cars very cheap, with running costs the obvious catch.
