This is the GTAm ("m" for modificata).
If you go for the "m" model, rear seats are deleted in favour of a roll cage, Saebelt 6-point harness and carbon fibre seats (the seats were already available on the Quadrifoglio) and Alcantra dash.
Single nut wheels, carbon ceramic brakes, 540HP, and aero designed by Sauber Engineering (Alfa's Formula 1 partner), along with Akrapovic titanium exhaust.
Other things thrown in include a helmet and racing suit in special GTA livery, and admission to a special driving school in Italy, etc.
Only 500 of each model. Won't be cheap, but man what a car.
