Main points:

1) Wants GTAs to compete directly with M series BMWs and S line Audis.
2) Doubling Alfa sales to 300,000 in next 5 years.
3)159 and Brera might be sold in US.
4) Wants GTA badge to have credibilty.Taking inspiration from the 60s cars,he sees reduction in weight as the way to go.
5) Wants to introduce more extreme 4 cylinder cars to compliment the high end V6s.
