Given that people were still buy SUVs and driving when gas was over $ 1.20 per L vs the $0.99 current.  Then I would say yes people are willing to pay for it in gas at least.

I am one of those rare sedan drivers - I have a mid size car that can seat 4 adults comfortably or be used for an Ikea run if necessary.  I don't get the desire for these bigger cars
