My bugeye's interior is plenty nice enough for me, cheap or no. I actually prefer its stark functionality over some "prettier" dashes in the Ford/Nissan/Toyota rentals that I've had, recently. (some cheap materials there, too, on the Fords)
Is it an Audi level of niceness? Not even close. But that's what you pay for in a $40K+ car. I'd much rather have an "acceptable" interior and have the money put towards the mechanicals.
But then, that's why we're all here, right?
