The VIN of my 92 400E also shows it was made in Germany, but it doesn't necessarily mean it's a European standard car, mine is qualified for Canadian Standard.
I've seen quite a few 400Es and 500Es in Germany, even in China, in fact German need V8 powered cars more than us, I don't think V8 W124s were only made for North American Market.
99 BMW 540i 6-speed 110K Km

Still missing the days with the Benz, it kept me busy.
