Ladas were ok, they were just beefed up FIAT 124 models after FIAT won the contract to supply a suitable small car for Russian poor road conditions, beating the Morris Minor, and small Renault of the time. FIAT beefed up the suspension and rewired the car to household standards so that any electrician could sort it.
The winning touch that convinced the Russians was that FIAT flew in the cars to the demonstration ground and dropped them by parachute, proving how tough they were. A driver team then drove them off the drop pallets and did the demo. The competition delivered theirs in lorries, so FIAT's imagination won the day.
It was an amazing contract, because it included building a new city as well for the workers to build the cars in a giant factory, the city of Togliatti, named after a well known Italian communist, though Russia calls the city Tolyatti.
