If you set aside better gas mileage, more powerful engines, better in-cabin materials, more driver technology, and much better objective reliability records - yes, I guess GM was better in the 80s and 90s.
I'd say Government Motors was at their best in the early 2000's. But then they took my and your (if you're a tax paying citizen) taxpayer money and became a drain on American citizens. When that happened they became lazy and unaccountable.
If you've followed the latest generations of SUV as an example, you certainly can't have the "reliability" word in your description. AFM, A/C blow ups, etc.
Call that bland grocery getter what it is.....an Equinox, or whatever.
