A crazy car for an insane amount of money, yes, but on the right road the Alfa Romeo Giulia GTAm could be the most exciting saloon car we’ve ever driven. And on a track it’s even better still, with huge mechanical and aerodynamic grip, a delicious soundtrack from the V6 engine, a brilliantly involving chassis and heroic brakes. Best of all, it looks a million dollars in the flesh. Which is just as well given how much the Alfa costs.
