I disagree with you on the build quality front. The Fabia still has the GP licked when it comes to quality of materials and general put-together-ness, but the GP is a whole hell of a lot more fun to drive, that's for sure!
That said, definitely the best Fiat for fit and finish yet. I'm glad they didn't try to pretend to be VW like they did with the Stilo. The Stilo was (is) a miserable failure. They tried to make it like a Golf, by using soft touch plastics and making it handle like a bag full of sh*t.
As it turned out the plastics weren't up to much, and the money they spent on them was robbed from the styling department.
Hence no sales.
Anyway, I'm pleased that there are no chrome plated door handles on the GP.
