You have not driven well driving cars if a 6000lb crossover is the pick of the litter. GM really went crazy with its Ultium SUVs by making most of them 77-78" wide with huge tires but there's only so much you can do mask the mass.

Have you driven a Miata? Even if the ZDX is objectively better in every way (which I doubt, but I could be wrong), I suspect the Miata will be subjectively better when rated for "is it fun to drive".
