We have owned 14 SAAB over a period of 40 years. Most of these cars were well-used (only three new out of all those, and two were leases) when we got them, most with mileage in the 75-80K range, which we then drove, in most cases, to twice that. Nobody.... but NOBODY ever gave SAAB a good rating. But the strange thing is, we never experienced many maintenance issues other than the routine scheduled items, and the things that fell outside of that were never break-the-bank, or anything one would not expect of a particular vehicle at whatever the age / mileage it occurred.
We are currently driving an '04 SAAB 9-5 wagon with 127K on it, bought as a CPO vehicle with 21K, and have never owned a better car. We are looking hard at the VW Passat TDI as our next ride. While we regret the passing of SAAB, I don't think we'll have any hesitation about buying VW, if it comes to that. Don't draw conclusions from ratings without understanding what's behind them.
