Hi,
Guess the reason why Saab is not as common is becos its a Swedish
car. And the most famous swedish car is of cos volvo.
Germany are well know for their technology, that's why for those
who can afford 150-200 over k, most will go for presitige, which
generally will drop to Merz, BM, Audi or even VW.
Didn't know abt Saab, but drove a 1996 Merz E200 and 1997 BMW 316i
before. If wanna some opinion of these cars, then maybe i can
help.
