Beautiful pic!
The answer you are looking for is probably BMW 1800 Neue Klasse and it brought BMW out of bankruptcy.
However, there are so many different stories about the bankruptcy save! Some say the Isetta brought them out of it, some say the 700!
BMWs 6 cylinders were just too expensive! Beautiful, luxurious and ahead of its time, fuel efficient too, but expensive. They were heading for bankruptcy and had to build something more economical!
The new class (Neue Klasse) cars, of which the 1800 is one definitely made good business for BMW and from there, it began to really grow in leaps and bounds, the 02 series, the CS etc. until eventually the 'series' nomenclature began (3,5,7 etc)
BTW, this thread is becoming very interesting! The pics, the data.
If I am correct in my reply to the above car and question, can we have another member give us a pic? I have posted too many already!
Let's see what else we have!
