is the saab 2007 9-7x a good suv

That all depends on your perceptions, I suppose.
If you consider a Chevy Trailblazer or a GMC Envoy to be a good SUV, then you would also consider this “Saab” to be a good SUV since it was built on the same assembly line in Moraine, Ohio and is mechanically identical to the aforementioned vehicles.

Consumer Reports rates the 2007 GMC Envoy V-8 as “Worse than Average” in terms of reliability, with the all wheel drive system being the major trouble area. Since the V-8 powered 9-7x is essentially the same vehicle (albeit with a different grille and a different dashboard), you should consider the 9-7x to have a similar level of reliability.

It’s a rebadged Chevy Trailblazer/GMC Envoy. I’d assume that those were cheaper.
