Funny, in my 06, I never have had any trouble with the cup holders. Best I think I've ever had in fact. They hold the big bottle of Aquafina, and a travel mug very well.
06 Rubi with some sort of double ended, chrome knobbed, cross threaded, infinitely adjustable, frequently breakable, worn out flammywhammers zip tied onto it.
It used to be a jeep thing... til that sh!t broke!
