On September 26, 1966, a meeting was held between the management of SPC (state production cooperative) Balkankar and representatives of the Italian automobile company Fiat.
On November 17 and 18, 1966, the sales manager of SPC Balkancar and the Fiat representatives negotiated a finalized version of the contract, which resolved the earlier impasse caused by the steep demands of the Bulgarian side.
After the Bulgarian side was trained in the assembly of the Fiats, it was decided to choose a Bulgarian-sounding trademark for the cars.
On March 12, 1968, the first Fiat 850 cars based on variant 2A were received at the factory as complete knockdown kits.
Between April and May 1968, Bulgarian engineer Dimitar Damyanov was sent to Turin to sign a contract with Fiat regarding the delivery of welding and assembly machinery.
