"And Santana is actually the former Hisparo that is renamed."
No, Sir, Santana assembled Land Rovers, so the inspiration for Santana is the Defender. If you want further proof, remember that in Brasil when they anticipated a mega-contract for light vehicles with the Brazilian Army, the romanians associated themselves with a Miami investor (because that's the kind of friends they have), while Santana PS-10 was brought by a Brazilian company who bankrupted recently. And in fact Aro itself was modelled mechanically after Defender and stylistically after an obscure Wagoneer prototype. This was the official policy, in Ceaushescu's words, "for the internal market we can even copy our mother" and, like any bad thing it escalated, thus "for the internal market" became ""for the socialist markets", then "for the trade with close friends", then"for trade". If you find any romanian original technology tell me, so I could kiss her.
