Ford Fiesta ST or Audi A4 1.8T 190

[cpfcwill]

Its time to buy a new car. I currently have a Ford Fiesta MK6 1.4 Flame and I am wanting to upgrade to something with a bit more grunt. I love Fords so that is why I am contemplating an ST however I like the look for the A4 1.8T 190. So i'm just looking to see what people's opinions on these two cars were and if there was anything I should be looking our for when buying either of these cars.

Thank you PHers.
