With all this controversy surrounding the Volkswagen Group and the EPA investigation regarding its diesel engines, who knows what the future holds for oil burners in the US. BMW was relatively late to the diesel game, although they did offer a diesel powerplant in the E28 5 series back in the 1980s. However, the 1990s were petrol only for the US market. So that begs the question: how did this 725tds make its way stateside. Cars like this under 25 years old that weren’t originally intended for US sale are always a risk in the used market, but somehow, this one got registered in California, a state known for its strict emissions rules.
