Depends, Mk7 on regular Fiestas but ZS with trim packs and the ST look far better, not a fan of the chrome grill at all, plus some of them the wheels are just too small, plus the original ones had the red dash lights and computer light which imo is better than the mangey blue
And I am the opposite. I like the red/pink hues of BMW interiors. But the fiesta doesn't pull it off and the blue looks nicer to me.
What I can say for the mk7 though is the petrol variants are bulletproof. Sigma engines don't ever want to die really.
