I bought the Sable for quite a nice price. Except for normal maintenance it's always running smooth and every time it's really nice driving it. The only bad thing I have so far is the alarm which seems to have his own life. After disconnecting the horn it doesn't bother me or my neighbors.
I think the engine is quite slow. I'm driving on LPG because the price of fuel is quite high here. Maybe that's the reason it's a little slow.
Another bad thing are the standard speakers. The sound is terrible flat. Problem solved with putting a sub woofer in it.
What's really perfect is the suspension. Very comfortable, but very good in sharp turns.
I think the dash looks pretty cheap. A lots of plastic, but that's quite normal for an American car I guess.
