I don't understand why anyone feels the need to compete.
Mini weighs 1175kg, Saxo weighs 935kg.
Mini One has 90BHP. Saxo VTR has 100BHP.
So the MINI has less power and more weight. It happens to have worse fuel economy and is markedly slower. It's not going to win a "Traffic Light Grand Prix".
It's still a nicer car tho. There's no comparison on build or image. Similar handling.
I'd take the Mini every time, but try and open your mind a bit dude
