Perhaps, IF you talk to someone who has owned a FLEET of the SAME model(s,) but certainly not to someone only owned ONE of them. Just because you owned ONE that was problematic, or was not problematic, does not mean the ONE someone else buys will be the same, be it good or bad.
For example you keep harping about bad GM vehicles when obviously most people who are CURRENTLY still buy more vehicles from GM than any other brand, do not agree with your assessment of the one or several that you may have found to be problematic. Good be you abused, or did not properly maintained, the one or few you owned.
A manufacturer does not continue to sell more than any other manufacture of the same product if all they made were turned out to be problematic, dummy.
