Correct me if i am wrong but here's my impression already of the 3 vehicles:

Fiesta S - Good performance & driving dynamics, "bang for the buck" if compared between the swift & rio hatchback

Rio Hatchback - More on comfort & convenience, already dressed up straight from the casa

Suzuki Swift - Cheapest acquisition cost without sacrificing driving dynamics and comfort/convenience/exterior looks/features

Hirap mamili!
