Are buick gs good cars?

Yes great cars, the 400 are fairly expensive, compared to 350 , The best buy right now is still stock standard 69 to 71 skylark 350, 4 barrel, but convertible,you can still pick them up for approx $10,000 and you will never loose because when the top goes down the price goes up , but get one with rust free body, . But if you can afford a gs yes yes yes yes -------------.
