South Africa has a wonderful history of confusing the masses by producing limited-run models for the local market. For the most part these would have been motorsport homologation specials, where a certain number of road versions had to be made for a car to compete in the various standard or modified production car categories - think Capri Perana, Chevrolet Can-Am, Opel Superboss and the 530MLE, 745i and 325is from the BMW SA stable.
Alfa were not to be outdone though and churned out the legendary 3.0GTV that scooped numerous Group 1 circuit victories and the lesser-known hot mid-1970s Giulia 2000 Rally.
The Rally story goes that Alfisti using the 1600 four-door on the rally scene needed a bit more poke. At the request of dealers, the 2-litre engine, gearbox, brakes and limited-slip differential were removed from some of the 2-litre GTV 105 series coupes (sales of these were not great with both pricing and the launch of the new 116 Series GTV hurting) and slotted into the four-door Giulia. The 2000 Rally badge was slapped on this and to homologate 50 were meant to have been made. Recordkeeping was not great, but the common consensus was that only 40 were assembled and select customers snapped them up.
With the original 1600 running gear from these Giulias now homeless, the decision makers chose to fit this to the empty 105 Series coupes and borrow a badge from the Datsun 1200 Deluxe (Datsun and Alfa shared a paint plant). The Alfa Romeo 1600 Deluxe (105 Series) was born. Again, the production number is believed to be 40.
To confuse the issue that little bit more, Alfa Romeo then brought in another 1600 coupe option from Europe. Known as the Unificato, this too was GTV-like but being a later series 2, sported a 115 series chassis stamp rather than 105. Word is that around 200 of these were sold in SA.
