Nothing personal, but it would be tough to buy a bigger POS that the Saabs you are looking at. Obviously Saab WAS a small manufacturer, catering to a very limited audience, who were very loyal to their slightly odd and durable products. At some point they were purchased by GM. From that point on, they went from quirky, to garbage, in short order. Saab went out of business earlier this year. As an "Orphan" brand, no longer in production, depreciation accelerates, and parts availability becomes an issue. They are available as cheap used cars for a reason. You can anticipate the probability of extremely expensive repairs, poor reliability, and continuing steep depreciation. In particular, the later models are plagued by really bad motors, that often need replacement at the mileage range you are shopping in.
As for the reliability of the high end German brands.........it's just a memory. Mercedes and BMW build complex vehicles that are well below the reliability of their Asian competitors, and really age rather poorly. BTW, I'm talking real world reliability, not the horseshit data about how wonderful these products are in "initial quality surveys" or how great they are when then they are still covered under warranty, and the owner is getting treated like royalty by the dealer. Real world reliability info. by my measurement, starts at what kind of product is it when it's 5-7 years old, and 60-80K on the odometer. We have reached a point where any manufacturer can build a car that doesn't suck while you are still paying off that 60 month loan. By the time a mid level Beemer or Mercedes reaches your price point, it can be a real ticking time bomb. It may run the next 50,000 miles with nothing but oil changes and tires, or the repairs may quickly exceed the purchase price. BTW, this also applies to lesser priced German brands. I am dumping a 2003 Passat shortly. The car is a pleasure to drive, and a nightmare to own. It was $6K with 90K miles on it, when I bought it 2-1/2 years ago. It has been extrodinarily unreliable, suffering from all the usual problems these cars are infamous for, and has needed roughly $4K in repairs during the time I have owned it.
As a 'stachian, I can't see another Eurotrash car ever darkening my driveway, ever! They are, almost without exception, one of the poorest transportation choices you can make.
